I have huge problems with my dedicated web server.
I mentain a web site which server mainly mp3s and videos. Daily the site servs 3000 downloads. The downloads are served by nginx, so apache2 servers only the pages.
The problem is that the load on the server gets as high as 60. A simple restart will fix the problem for 24 hours (load under 1) but after aproximately a day the load starts to grow again.
I also have webmin configuration software installed.
At first, I thought I have some cron jobs who overload the server, but crontab -l reports as follows:
53 3 * * * /etc/webmin/webalizer/webalizer.pl /home/resursecrestine/logs/access_log
50 3 * * * /etc/webmin/virtualmin-awstats/awstats.pl resursecrestine.ro
This should be ok I think.
Another thing that I noticed is that every hit on the server causes a "File does not exist: /htdocs" error in apache error log. This should be due to the DocumentRoot directive not set corectly... I checked and the DocumentRoot is correct :¦
I also paste the output of ps -el and ps -ef

I also noticed that the server is very responsive even if the load is 60. The IO WAIT is also most of the time 0.0%
Please give me a clue of what the heck is going on...
Thank you
The "File does not exist: /htdocs" error may not be related to this problem, it can be due to a broken image or something like that. You would need to check the access log to find out where it is caused, by which resource.
I suggest you to enable the mod_status module [httpd.apache.org] in the Apache, so you can see a real time status of each child process. The status will include the status of each child (idle, working, reading, writing), the last resource being served, the time needed for that and so on. With this information you might be a bit closer to spotting the problem.
