Hi guys, Since one month ago that I'm receiving many emails with notifications from my server about CPU overload. Can please someone tell me how can I detect the account or issue that is causing this overload? I use WHM and also have access via SSH. This is a copy of the last email: IMPORTANT: Do not ignore this email.  This is cPanel cpuwatch on server.enigmahost.org!  While processing, the cpu has been maxed out for more than a 6 hour period.  The current load/uptime line on the server at the time of this email is  10:49:04 up 233 days, 22:06,  0 users,  load average: 2.20, 2.34, 2.49  You should check the server to see why the load is so high and take steps to lower the load.  If you want stats to continue to run even with a high load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run /usr/local/cpanel/startup Code (markup): Thank you
In WHM goto system processes. In there you should be able to see the process(es) ripping up your CPU. Another problem could be another user on the same node as you who is causing the problem (identical processes running, too many, etc). A simple fix would be to disable all ssh/shell access to your clients temporarily and go in through your own ssh as root, and look at the processes running then terminate the processes which are redundant. Secondly, look at which client is using the most bandwidth, there is usually a direct correlation between bandwidth usage and cpu load. Cheers,
Thank you for your reply zebulon! Is possible that my server is under ddos attack? Can you or someone help me read my server stats?

Just travelling now and I hate using the crackberry to diagnose issues. Later this evening I'm jump onto my laptop and get you an answer or atleast a possible solution.
Thank you! Here goes some more info... Daily Process Log: http://screensnapr.com/e/HF8GoI.jpg http://screensnapr.com/e/Ws4nb1.jpg MySQLTuner screenshot: http://screensnapr.com/e/DfxCLC.jpg
I see gzip is running and taking a lot of power are you performing a backup? You may also want to try limiting execution time it prevents scripts from wasting server resources. Let me know if you still need help
