We're trying to find a bug that will cause multiple PHP processes to be run at the same time and thus eating up the CPU resources for around 5 minutes. During these 5 minutes, our server will totally inaccessible.
We can't seem to replicate the problem and not to mention seeing the same problem on our staging server. My question is will installing xdebug on our production server help us finding the root of the problem? Will xdebug affect our production servers performance?
