we need to optimize our magento based web server. I did the most i could to optimize it but sometimes(1 to 5 days) the server crash due to CPU Overload and i don't know why. The task is detect the problem and leave the server optimized and working fine.
The load average of the server is 1-1.5 but suddently goes up to 40 and crash.
The most of traffic we get come from CPC so we get high problem when server crash.
If you can speak spanish is better for me.
