    Hello, I have been running a little hosting company since 2 years ago using Cpanel without any major problems, but this last week since an update to the latest version I'm having this little problem in some hosted sites.

    The sites keep vising by itself increasing the load on server, for example:
    load average: 56.07, 47.70, 30.39

    When I see the top I always see a site generating the issue, if I go check the access log for that site I can see something like this:

    64.XX.XX.XX is the IP of my server
    64.XX.XX.XX - - [27/Mar/2015:05:36:25 -0700] "GET /wp-content/uploads/2014/12/constructo-logoV4-footer22.png HTTP/1.0" 404 16429 "-" "-"
    64.XX.XX.XX - - [27/Mar/2015:05:36:25 -0700] "GET /wp-content/uploads/2014/12/constructo-logoV4-footer22.png HTTP/1.0" 404 16429 "-" "-"

    Try using top or ps command to figure out which process is increasing the server load. Whether it is mysql or apache or PHP process. On that basis of that you have to tweak/optimize your server settings.
