Httpd High Load

High Server Load / High Swap / Lots Of Httpd

Feb 20, 2008

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)

High Server Load - Httpd Processes

Mar 23, 2008

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?

I tried to kill all "nobody" process, and then is everythin OK but after 5 minutes is happening again, the worst thing is that every minute this cpu usage is increasing untillall my web sites crashes (just website , shoutcast service works fine)
the process os "nobody" is: /usr/local/apache/bin/httpd -k start -DSSL

Server High Load/high Mysql Usage

Jul 2, 2009

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 Cpu Usage (httpd)

May 31, 2008

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 Load From High Iowait

Jul 2, 2008

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

Server Load, And Tracing Httpd Processes

Feb 28, 2008

I have a server that has server load showing at 25-40 (once it was even 53!), running like that for hours. The server has 4 cpus - and yet the sites on the server seem to run fine when I check them. What I'm wondering is, what exactly is load in this context; and how can load run so high like that without the server crashing?

According to top, the load is caused by httpd processes running under user 'nobody', that often take up double digit CPU percentage.

Does Apache always run under 'nobody'?

Is there any way to trace an httpd processes - which account it's for, or which physical script or URL is calling it?

And for top itself, the TIME field on one server of mine is in the format xx:xx (e.g. 3:25), on another it's TIME+ and in the format xx:xx.xx (e.g. 30:02.77). What exactly does this mean? I would asume it's minutes:seconds and minutes:seconds:hundredths, but while watching top it doesn't seem to correlate with that.

Httpd Failed - Sites Don't Load - Host Can't Help

Jan 9, 2008

The last 2-3 days my websites on my vps all started acting funny. Randomly throughout the day they will all just stop loading. If you go to one of my sites they will just load and load and load and eventually time out after 5 minutes.

To fix this problem, all I have to do is reset Apache in my WHM. Everything will be fine for awhile until it decides to stop loading again.

I've been talking to tech support for 2 days. They're out of options. They tried banning some IPs as they thought I might be getting hacked. They tried moving me to a different host machine. They've checked all my logs... there are no errors or problems with the vps. The server load is always very low. Memory is always very low.

I run about 15-20 websites on this VPS. Two of them are vbulletin (v. 3.6.4 and v3.6.8) and all the rest are wordpress).

My VPS is hosted with ServInt.

Server Version: Apache/1.3.39 (Unix) PHP/5.2.4 mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4
mysql (5.0.45-community-log)

I get these emails all day:
httpd failed @ Wed Jan 9 06:10:42 2008. A restart was attempted automagically.

I am completely out of ideas and options. Can anyone think of something? Think outside the box... make random suggestions. I don't care, I need to try something.

I most recently added 3 or so brand new websites to my vps about a week ago. However, they are just running wordpress so I can't imagine they're the problem.

Plesk 11.x / Linux :: How To Stop High Number Of Httpd Processes Crashing Server

May 17, 2014

Our server is running; Plesk 11.0.9 and CentOS 5.7 it has a Q8200 CPU @ 2.33GHz and 2GB of RAM. Now there are just two websites on the server plus a couple of redirects/forwarding domains, although lots of domains are still on the server but turned off in Plesk. Both websites are OSCommerce sites and I just need to keep these sites going until the end of the year when we will switch to our new Joomla based website.

We have seen an increasing number of server crashes and after various checks of the logs, fitting a new BIOS battery, check of the hardware by EasySpace who host the server, installation of ClamAV, LMD and RKHunter (which did find some Trojans and Suspect software), I have traced it down to some external Http activity that is taking all of my CPU time and RAM. Here is a screen capture of the Htop listing and when I killed these processes the CPU and RAM went back to normal. The problem is that I usually have to restart the HTTPD service and sometimes things get so bad that the server crashes and I have to request a power cycle.

High VPS Load

Jun 24, 2009

My VPS holds about 80 domains and low-use accounts.

Every night, from around 1.30am, the load suddenly skyrockets and will usually be around 5 to 10 for a few hours. Occasionally it'll spike to 30+ for a few minutes.

I had some antispam software running, and a couple of other packages (mail queues, mail manage etc), so I disabled all of that and removed all the crontab entries etc.

It's not really made any difference.

I can see the load stats going back 8 hours, as part of the ASSP spam package (I've just left the ASSP server load cron running just so I can continue monitoring it!)

Can the apparent load on my VPS be caused by other VPS's on the same node?? So in reality, my load is fine but is being affected by other people's VPS's?

I hope that makes sense. I'm 99% sure that my VPS is 'clean' (in so far as cron entries)

I'm asking the question because I took a second VPS on the same node and that one too has high loads overnight when there's nothing running on it (ie, no add-on software, no Cpanel accounts added)

What Should I Consider A High Load On VPS

Jun 30, 2007

Just signed up for a VPS with solarvps, which so far is lightning fast compared to my shared reseller account with RZ.

I want to create a script which checks the server load and drops me a text message on my mobile if the server load hits a certain level.

Just wondering what I should consider a high server load?

The server is the JupiterLX UK one from solar vps with over just over 800mb of SLM RAM.

High Load

May 11, 2007

Im in a VPS and everyday at the same hour goes very slowly due to high load problems.

The main site is a vBulletin forum and I get this error:
Too many connections

Ive change some details in my.cnf:

Quote:

max_connections=500
max_user_connections=70

But it didnt solve the problem.

This high load occurs at the same hour, I think that it is a cron job related problem, but this is my /etc/crontab

Quote:

# cat crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

High Load

Dec 30, 2007

How can you tell if your server was a victim of a DDOS attack? Server load goes so high that you cannot get in via SSH, and the server has to be power cycled to get back online. When it comes back online, load goes back up, we shut apache down, and the let the load come back down and then restart apache and everything is fine. Any way to determine what caused the load to skyrocket? System has APF, BFD, and mod_evasive installed.

Rsync - High Load

Jul 25, 2007

I am using rsync to transfer files (tar.gz) between servers. However, it makes server load increasing 3-4. Normally, server load can be around 1, but when doing the transfer, it can go up to 5+

Is there anyway to reduce the load when doing rsync?

Aug 23, 2007

I am just a beginner and it is about a month that the mysql loads on my server is so high , I have checked the mysql processlist via cpanel and there is no account that takes high mysql and make it high , and even I have checked for any possible rotten databases. but still the server load is so high and I can not control it , even when I restart it just after a minute it goes up again.

just the spamd command takes a high CPU usage sometimes. what it should be from? the spamd for a special account!

I need to optimize mysql , and need help. please do not tell me to hire an expert , just help me thanks

and another question is that how can I check which account is sending spam and stop it?

High Load Average While Using SCP

Oct 22, 2009

I have to move about 50 GB each night from one server to another.

This is the command I'm using:

Code:

/bin/nice -n +19 scp -c blowfish -l 18000 -P 22222 root@XX.XX.XX.XX:/backup/dailybacks/*.tar.gz ./
There is no private lan so i have to use internet. I'm using blowfish, which will reduce cpu load, and also limiting bandwidth transfer, usign -l 18000. How ever, I still do see some high load averages..

Do you have any other suggestion to optimize CPU performance while running scp?
