High Cpu Usage (httpd)


I noticed high cpu usage on my server since a couple of days ago. I neither updated software nor changed the configurations on the server. The server load was about 0.5 ~ 1.0 but now the average CPU load does not go below 5.0

when I stop apache (1.3) the load goes down and as soon as I start it up the load start increasing.

I checked for DoS but it seems nothing exists of this type.

I tried to follow the access_log file but from the first view nothing is strange there.

I don't have any control panel on the server. just Apache, FTP and SSH installed.

High Server Load / High Swap / Lots Of Httpd
I have a cPanel server with 4GB RAM

My server hangs time to time, once or twice a day. This is the last status when it happens.

Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %

When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.

So I "killall -9 httpd", I had to do it 30~40 times

#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.

Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.

At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)

Server High Load/high Mysql Usage
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.

An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.

My current server stats:

Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9

Website traffic stats:

15,000 visitors/day
150,000 pageviews/day
Serving videos

I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.

High Server Load - Httpd Processes
a topic long time ago that my server load is frequently high.

I'm talking about something like this
Server Load 158.86
Memory Used 28.2 %
Swap Used 99.57 %

[url]

The only way to solve this problem is to identify the load earlier and kill all httpd process. What I did was

#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.

On previous thread, I tried to update mysql & php and it works,

Right now again I am experiencing high server load again...

I'm very sure it's caused by httpd but I am still unable to find out the real cause of the problem and which account user is the culprit for causing this high load.

Can someone assist me by telling me where/how to begin with?

the process os "nobody" is: /usr/local/apache/bin/httpd -k start -DSSL

What Causes High CPU Usage
I know about high CPU usage and how it works against a webmaster when his host decides to suspend an account over this.

My question is what kinds of scripts usually cause CPU Usage to bulk up.

Basically what the script is doing, that just makes it happen.

I tried Google, but i guess poor choice of keywords .

Named High Cpu Usage
Since yesterday named started to use more cpu than usual. Techs "refuse" to work with that issue and saying that its's normal. Though all the time had no problems, haven't added hundreds of domains yesterday and there were no changes from my end.

There was one change from techs side however.

"the MX record for the domain was going to localhost, rather than the domain name. I have changed the MX record to domain..."

Anything I should check? Logs doesn't provide anything valuable, just notices.

Causes Of High Resource Usage
I am running a youtube clone on a VPS with 512mb ram at Lunarpages.

Whenever I log into Plesk, I find that my system usage is extremely high. 90%++ even up to 100%. However my CPU usage is often less than 5%.

This problem often occurs when there is slightly more visitors on my site. I am talking about only 30++ visitors and this problem will occur and my site slows to a crawl and I have to restart the VPS.

The script or the server?

High Memory Usage
I purchased a VPS at wiredtree to upload a site that is in the works so that it would be "ready" once it was launched (had it sitting on a shared server before). So I have this domain on there, as well as a small wordpress blog. In total I'm get a very miniscule trickle of visitors to these websites (as they are not officially launched), around 100 visits per day, many of which are only 1 pageview visits.

My problem is, my server is already idling over its memory limit of 256mb. This is causing major slowdowns, and processes like cpanel are constantly be killed and I can't login.

Does anyone have any idea what is causing my high memory usage? I just can't image that the visitors I am getting are doing much, as for the majority of the day I have absolutely no one viewing my domains, yet my memory usage is still over the limit.

Wiredtree support says its up to me to optimize my msql/php scripts etc for low mem usage, but I don't see how this will help when there is no one using them in the first place.

Cpanellogd High Mem Usage
For some reason cpanellogd always had huge memory usage in the realm of 40-90% when running logs for one particular site, which inturn sends the server load to 25-40.

What can cause this? I have delete logs after stats run enabled and all the usuall.

Load Is Low CPU Usage Is High
I was wondering is someone can shed some light on a curious situation for me. I am running a linux server (Gentoo) and the CPU usage spikes to 90-100% but the load of the server when viewed by top is only 0.4 - 1.5 (max). The memory is OK with .5 gig free and there is no paging going on. So my question is: Is this server over used or not?

Mysql Usage: High CPU %, How Do I Find Out Who's Using What
just noticed mysql cpu usage has shot up from its usual 5-10% cpu to 30%+. domains are as normal and no extraordinary php processes.

any way i can tell what users are most heavily running mysql? (as in number queries / slow queries etc?) i know mysqladmin processlist but that only gives me a snapshot, whereas i want to see over 24 hours, who used mysql the most...

High Dom0 Memory Usage On Xen
I'm running hypervm on xen a centos 5 64 bit box.

The problem I'm having is that after a couple of hours of uptime Dom0 seems to have used up all of it's available memory i.e:

I have disabled the memory balloon driver in the xen config and set dom0_mem=1536M in grub.conf, i.e:

default=1
timeout=1
splashimage=(hd0,0)/grub/splash.xpm.gz

CPanel Server, High CPU Usage From PHP
I just moved from a P4 Dual Core (2mb cache) to a Dual Xeon (512k cache) and everything has gone to sh*t.

I had the server optimized/security hardened (for the most part) and last night, I had a RAM upgrade to 4GB.

As soon as the server came back up after the upgrade, CPU usage was into the mid hundreds. RAM usage is fine....

Presently, I'm showing PHP using a ton of CPU. I tweaked mysql a little bit, and that helped slightly.

Also, last night, I had the DC run diagnostics on the RAM and hard drive. Both check out OK.

Here's the specs:
2x Intel Xeon 2.80GHz
4GB RAM
cPanel
CENTOS Enterprise 5.2 i686
PHP 5.x
MySQL 5.x
Exim

When viewing TOP or status in WHM, php scripts use the most CPU. With average CPU load around 60+

High Usage Of Server Resources
a few times, my host contacted me and said that my account is suspended due to high usage of server resources.

I have 3 sites using SMF (a forum script.) I have around 8500 visitors and 3 million page views per month in total.

can this be a reason of high usage?

if it's what's the meaning of terabyte traffic limit ? which you can never use

I asked to my host if they could let me know what's causing high server resources usage. here is the answer:

We do not know which domain or script caused this high usage, it is your responsibility to investigate. I would suggest that you go through your raw access logs to see the most requested pages and then investigate those further. After you find the pages responsible, please optimize them so you are not using so many server resources.

so if a host wants simply to restrict traffic limit, they have a pre-reason under hand.high server usage! yes but how will I know that? how will I trust that it's true?

when I ask why my sites are down, they can easily tell me that it's because of high server usage!

CPU Usage HIGH - Spamd Child
I have just moved my sites from shared host to a vps. After several initial problems (cpanel issue, config not set up correctly, memory spikes and sites down every morning due to backup and stats) I thought everything was going to be ok. hmm.

My server load starts off fine first thing (less than 1) then creeps up nearly 1 per hour, ie been 3.5 hours now and it is at 2.57. Sites are ok at the moment but yesterday load got up to nearly 7 and sites were extremely slow.

CPU usage is HIGH for one site and goes up very quickly throughout the day. Yesterday it reached well over 90%. First thing today it was already amber and showing 14%. It is now 70.54% and shows below it :

Top Process %CPU 80.2 spamd child
Top Process %CPU 79.8 spamd child
Top Process %CPU 79.4 spamd child

I have a ticket open and they (Liquid Web) they are not sure what the deal is, but are apparently monitoring it to see if they can isolate the cause of the problem. But that was a couple of days ago and now the ticket is due for closure.

I telephoned them (expensive as I'm in the UK!) and raised my concerns, but was just told that everything looked ok on the vps, cpu usage was in fact not high and to ignore the warnings.

So, I am posting here to see if anybody can help me get to the root of this.

I understand that spamd child is to do with email / spam assassin?

My problem is that this is the first vps I have had and don't have a clue now where to go or what to do.

Anybody understand about spamd child that can explain it to a poor dumb blonde and how to fix it?

Upgraded Network Port And Now CPU Usage Is Sky High
Today I upgraded my dual opteron dedicated server from a 10mbps port to 100mbps. While the number of apache access have dropped by about a quarter my CPU usage has increased also by about a quarter, my CPU is touching on 95-100% now.

What’s most likely to be the cause?

What’s also interesting is my network port is only showing 20mbps usage, nowhere near the 100mbps its been upgraded to.

Exceptionally High Memory Usage On My Dedicated
I'm currently running vBulletin & two wordpress powered blogs on my box. Number of simultaneous users is about 200~250 and about 15~20 logged in users.

The memory usage is constantly in the range of 1.8 GB - 2.00 GB. Considering that total physical RAM my box has is 2 GB, the memory usage, I believe is exceptionally high.

The same site was running very well on shared hosting environment and also on VPS [with just 512 MB RAM] very fine.

What should I do to bring the memory consumption to minimum (required to run the site well?)

High Usage Email System Query
One of the projects I will work on will require to process 50,000 emails a day. Most of these emails would include attachments and the challenge is to process them and put all the stuff into a database for the application to use.

My biggest concern is spam and we cannot afford to lose out on legitimate emails. One way of configuring the setup would entail checking emails for the specific types of attachments and piping it in.

However I was just wondering if someone here has dealt with this volume of emails and also what are the spam limiting options available (even commercial would do)

May Server Crash Due To High Load With Low CPU And RAM Usage
I have server load like 40.

Nothing lags.

Server has RAM usage 20% and CPU usage goes up to 25%

Swap isnt used at all.

Should I be afraid of server crash incase server load goes up to 60 or 80 without ram and cpu usage rising that much?

Dreamhost PS High Resource Usage Problem, Is It SCAM?
I upgraded my hosting to DreamHost PS (http://www.dreamhost.com/hosting-vps.html) about 7 days ago, and after 3 days of evaluation i find no interest about it and decided to downgrade. But they rejected my request saying that the resource is too high, then came the long negotiation.
My question now is, would domains parked(not hosted) at dreamhost ate up memory of my PS?
Phase 1: Why didn't anyone warn me before the upgrade?

I wrote:

I found a few unreasonable facts about your statement of rejecting my downgrading request:
1. Dreamhost tempted me to upgrade when I was doing fine with share hosting;

2. Dreamhost didn't warn me with any condition or term of any kind, including downgrading would be rejected if memory reach a certain degree;

3. from the facts stated above, this upgrading thing is a total scam.

##comment: The upgrade took only a click of the button.

And their answer:

I'm sorry to hear you feel this way Ruiz. However, your accounts resource usage is above what will work on shared hosting. If we were to move you back, one of two things would begin to happen:

1 - your domains would affect the stability of the web server, slowing down other customers sites, or taking them down completely

2 - your own sites would begin to fail due to the high resource usage.

As such, we can not move you back until you've brought that usage down. However, I can understand why you would feel the way you do. As such, I'm willing to add a $15/mo subsidy to your PS service. What this means, is that the basic 150MB/MHz you have to pay for will be free, all you will need to pay for would be any resources you allocate beyond the first 150MB. If this is alright, let me know and I'll go ahead and add the subsidy to your account.Phase 2: Why my hosting suddenly ate up so much memory?

I said:

I haven't recieved any email mentioning that my domains are using too much resource BEFORE THE UPGRADE for almost ONE WHOLE YEAR, how come suddenly they are? Is it some kind of malfunction or misconfiguration of your PS that causes the problem? If it is, why should I pay for it?

They answered:

It isn't a "sudden" issue. Your sites have been using whatever resources they need for as long as you've been on the PS. It appears you've had spikes as high as 600MB of memory in your usage, and if you look at your graph over the last month: ...

Suspecting Server Is Causing High Bandwidth Usage
For the past few days, one of the server is causing a bandwidth utilization surge for the entire rack on almost daily basis. It happen for a few minutes and it went off then it will be the same thing again the next day. When the surge is happening, most of the servers on the same segment will be inaccessible for the few minutes.

The bandwidth utilization graph for my rack is recording an abnormal surge from (6mbps --> 90mbps) for the few minutes. My MRTG is showing 2 of the Plesk servers giving the problem but the NOC guys said it the Cpanel that causing the problem.

I tried logging in to both servers but could not find what's the cause for this.

Trojan Activity - Running Perl With High CPU Usage, With User Apache
Running programs named Perl with Heavy CPU usage, with the ownership of user apache.

We found the problem on Fedora 3 and Fedora 6.

In our case, it was the result of a Trojan activity.

Quick Solution

Check the cron jobs of user apache
crontab -u apache -e
*/1 * * * * perl /tmp/.tmp/tmpfile
delete the cronjob entry.
Also delete the file /tmp/.tmp/tmpfile
also added "apache" to the file /etc/cron.deny

That's all

High Load From High Iowait
I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.

I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.

Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed.
I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.

At this moment for example:

top - 09:00:36 up 15:43, 3 users, load average: 3.57, 4.60, 5.32
Tasks: 144 total, 2 running, 142 sleeping, 0 stopped, 0 zombie
Cpu(s): 10.6%us, 6.5%sy, 0.0%ni, 18.7%id, 63.5%wa, 0.2%hi, 0.5%si, 0.0%st

Httpd
I know that there are a lot of posts about this but... i have a problem w my apache... it was working fine until today... i get this e-mail from WHM whenever httpd fails... and its pretty often:

Quote:

httpd failed @ Mon Aug 18 16:23:13 2008. A restart was attempted automagically.

Failure Reason: Timeout while trying to connect to service

I wanna know how to check in the error log the entries of just today. because when i put "cat error_log" i start receiving things from last week and this is happening today...

i've tried /scripts/rebuildhttpdconf and then restarted, but still the same.
