I have some webs with 30K/40K visits each day (it's not too much)... A smaller CPU with 1Gb RAM with cPanel and Apache 1.3 worked perfectly, and now with a bigger computer and plesk I see this...

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.
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.
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 have 10 web sites running on my server, but they are really small talking about traffic, according to statistics, my "star web site" have 300 visits per day I also have a few shoutcast services running on my server, but i think ther are fine
According to cpanel, yesterday I had this cpu usage (only showing the top process) User Domain %CPU %MEM MySQL Processes nobody 79.10 25.07 0.0
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
i am using seperate server for sql .But my httpd server failed many time when i checked maximum number of httpd connection then my sql server using too many connection what is the reason of this problem . Is my sql server using as a slave in a ddos attack or sql server need http connection?
I've been having trouble with my VPS for a while now. In the QoS alerts page in Virtuozzo it seems to be a problem with numtcpsock and tcprcvbuf, mainly numtcpsock.

Anyone know of some good server load testers ( commercial )?
Im not looking for application based load testing, I need real web server load testing... need to see how much traffic this one site can take before it cries.
I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?
i have creat my new user and upload his files on it. but when i try this link:
http://ip/~user
i have this error and my friend say that your httpd have problem. but its my new server. how can i solve it ?
404 Not Found
The server can not find the requested page:
ip/~user (port 80)

I have 1764 pid started by httpd daemon. I think for some reason the httpd pid is not closing for me. How do i make sure that all of the httpd pid are closing.
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:

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.
I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts
I just got apache installed on my box and the process is running. However when I enter my ip address on firefox, nothing loads up and I get a timeout error.
I did a Graceful Server Reboot, but it seems httpd service not running yet,
I got this error after try to restart Apache..
" Restarting Apache Web Server Waiting for httpd to restart..............finished. httpd (/usr/local/cpanel/whostmgr/bin/whostmgr ./reshttpd) running as root with PID 3319 httpd has failed, please contact the sysadmin. "
and my Log:

I just stop httpd service for server maintainance , and disable its monitoring from whm services, but after some time it again start even i disable httpd monitoring and service.
I moved a domain of mine from one of my CentOS servers on my SoHo LAN, to one of my CentOS cPanel/WHM servers. Since the SoHo machine had been handling this domain's mail for almost 2 years (300+ mb of mail), I decided to continue running it from home.
The Apache daemon was stopped on said SoHo box following DNS propagation to the cPanel machine, but Apache was automatically started again after having to reboot the SoHo server. Before I got a chance to kill Apache, I got some weird entries showin' up in the access_logs.
I ask simply because I don't recall seeing a "CONNECT" entry in my logs before, and I've been at this for awhile. That or I've just not paid any attention. And what's with the SSL port?
I guess I'm just a little confused as to what was trying to be accomplished here...it hasn't returned since.
right ive got a server thats getting battered at the moment by lots of apache processes, ive moved sql off to a seperate box (with private lan so thats fine) but now i need to optimize/replace apache with something less intensive on resources, only problem is im using plesk on this server so i am not sure if i can change the webserver app?
Trying to troubleshoot an exploit where the code redirecting people to exploit sites is not in the website. I think a module is being loaded dynamically, but I am not seeing the entry point in the access logs. I restart httpd and the problem goes away temporarily.
Anyone see anything fishy?

It seems to be common that in httpd status in Apache 2.x except real connections you can also see multiple connections from www.example.com Is it a bug and if not is there a way to make httpd status to not show those www.example.com connections?
I have httpd down right now without any error outputted on errors_log my server is with 4 Quad-Core Intel Xeon 2.66GHz (16 CPu) and 16GB of RAM. Is running CentOS Linux 5.1 and Apache/2.2.8.
