Not good ....
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ?
Question 2 : Why i don't find high usage process in top command ?
Question 3 How can i resolve this problem ?

I have a linux server that is only hosting one site , and although the httpd and mysql are working well , then the server load is high and when I restart the server the server load is high till the swap accelerates to 100% and then it uses the memory alot.

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)

I've got a dedicated with LW.
I've had it for a while and during that time I've never seen the swap memory go over 20%.
A month or so ago, I had the server upgraded to 8GB of ram to make room for more planned sites.
Since then, the swap memory has gone rampant. It regulary goes to 93% used with less than 20% of the regular ram and really no load on the server.
I've contacted support twice about it and was told don't worry it's normal.
From what I've read in the cpanel forum, no it's not normal and may in fact be caused by bad ram chips and if it hits 100% could freeze the server.
There are no processes or users causing it, so It's something else.
Has anybody had this type of problem that they resolved and could share what they did to resolve it?

I've hired *name* to take care of my server, but it's just getting so frustrating, as it seems they can't fix my server/optimize it correctly.
I just want some input as to what the problem is here.
I got them to install lighttpd along with xcache.
After about 15-18 hours, the server's CPU slowly increases to be using 90-90%, giving me the 500 Internal Server Error.
I've asked them to optimize xcache and lighttpd, but I keep getting these responses:
Quote:
The should be pretty optimized. Xcache has limited optimization features.
Quote:
Lighttpd itself is pretty optimized, the problem is php. Php runs as its own binary and theres not many parameters that can be tweaked.
Is that even correct?
-------------------------
So I got them to enable apache, and disable lighttpd.
This time, it's the other way around.
My ram get's completely used up, forcing the server to use Swap; making the load shoot to 50+. CPU usage is fine the entire way.
-------------------------
This has been going back and forth, enabling/disabling lighttpd and re-enabling apache but a problem always comes up each time.
Am I asking for too much?
Server specs;
Intel C2D E6400
4GB Ram
There is only one IPB board on this server - nothing else.
Average users is 70-200 users within 15 minutes.
This is what I'm getting when lighttpd is on:

I was getting high load on one of our test machines -- it was high enough to where I couldn't ssh in. However, I happened to have a shell open at the time with top running. Load was very high and swap was full. -- afterwards, when I check /var/log/messages it looks as if the load affected the time (see below).
1) At first I was guessing that the load somehow affected the clock, but you'd think it would slow it down -- but apparently the pace of time was quicker?
2) perhaps the time was wrong in the first place - then upon reboot, ntp sync'd up properly.
3) time was originally correct but after the high load, it somehow erroneously sped up the ticks
Then again, from googling around someone on another forum was saying that the computer clock chip shouldn't ever be affected.
So my question isn't about what cause the load, but why was there a time descrepancy in /var/log/messages, and was it related to the load?

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.

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 .

I have server with P4 ( 2.4ghz) 2gb ram with cpanel and centos.
When I get more than 300 users online on my forum. Server load remains under 2 but Ram usage get's high upto 90% every 10 to 3 minutes. I have to restart apache in order to keep it down.
Currenty shows 67% ram usage in WHM and here is:

the probleme is that the memory server it used in totaly . after i was just 2Gb of ram , but sometimes the server lod arrive at 50% . for that i have added more memory (4Gb) , when i added it the memroy usage is always about 4giga sometimes about 3980Mb . the load is normal , but sometimes the server loas arrive at 50% or 60% (this is just in specific times) . after i have decided to add 2 Gb more , now is 6gb in the server . but also all the 6giag of ram is used , the load is normal but memory is all used , look to the top command

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.

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.

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?

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.

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.

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?

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...

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:
[root@------ ~]# free -m
total used free shared buffers cached
Mem: 1536 1516 19 0 993 247
-/+ buffers/cache: 275 1260
Swap: 16002 0 16002
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
hiddenmenu

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+

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!

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?

I have seen posts that some hosts suspend a user after they so many seconds of high server resource usage... I was wondering how this is done so that I can do this on my dedicated server.
