server load is higher than 40. is it dangerous?

server load is higher than 40. is it dangerous? our server has 4 CPUs. also where can i find logs....

A normal load average is typically 1 per CPU = 4 in your case.

You'll find most important logs in :
/var/log/
/etc/httpd/logs/
/usr/local/cpanel/logs/

This being said, if you don't know where the logs are, maybe you should consider to get management services - at least until you're comfortable enough to manage your server by yourself ?

few days ago it was fine. i couldn't find any mysql log from my server. i'm not sysadmin. but i use cpanel to manage my server. :D

 

[Batmunkh]

if i disable alternative configuration of suPHP it's fine. but htaccess mod_rewrite doesn't work. If i enable suPHP it loads server load very high. how should i fix it?

suphp is good for a shared environment with no very active sites. Did you try to use fastcgi instead ?
Also is it normal that azmn is running so many php processes ?

When running suphp, top -c will show the full path of the php scripts that are running.

When php is in cgi/suphp mode it is less efficient, so the load tends to be higher. If you change it to dso mode the load should drop, but that is less secure.

According to your output it looks like most of the traffic is from 1 user.
