    what sort of applications/websites are you hosting on this system? What is the output of 'top' if you can run that from an SSH session. That should give some good idea to what is casuing the load.

    Is 'krazyboy's website insanely popular? He may be running a malicious script.

    is that all the output?

    There are a lot of php processes - i assume that there are a lot of visitors to this website? Can you describe what sort of websites this server is hosting and how many visitors you typically are getting?

    well there you go - thats a lot of hits... PHP is generating the load based off the number of hits

    probably not a great deal. you can see if you can optimise your php scripts. Did you code the website?

    How many hours has passed today? If that's over 24 hours or even 6 hours, the server should not get such a high load.

    just hit the site - does take a long time to load initally. im not getting delay to the host - definitley looks like the PHP script is very heavy to load initally.

    Im not the expert here - but is there a caching mechanisim that could be employed here?

    Note the wa, what does iostat show for disk stats? moving your websites to another physical drive may help, or as previously mentioned getting the code being used optimized

    You Should know what is the problem from

    Let's see if the problem from apache

    Open SSH and type that command

    PHP Code:
    service httpd stop 
    This will stop apache

    now look at load average and see if it get down

    to run apache type that command

    PHP Code:
    service httpd start 
    if the load doesn't get down try to stop mysql

    type that command

    PHP Code:
    service mysql stop 
    look at the load average and see it get down

    to run mysql type that command

    PHP Code:
    service mysql start 
    and you will know what is the problem from

    based off the above and the output you psoted earlier - it is the PHP scripts that are causing the load.

    Is your site slow? If it is not slow/performing fine, you might not need to do anything. I mean load average of two is not a big deal for such server.

    It will also set your feet on fire....

    The worst that can happen -- the server will be done, and would need to be rebooted (this is really the worst)
    What you most likely see when load will go high -- your site will be slow, and maybe unreachable.
    If you see your site becoming more and more popular/load going up -- you might think into investing in optimizing the scripts, or depending on how much it would cost you/how much grow you anticipate, upgrading the server.
    Right now -- I would just let it be.
