Segfaults always happen. Only changes their frequency. Actually I have keepalive active with keepalivetimeout=5 on both servers. > 3. Which php applications are causing the crash except phpbb3? On the 13.1 server I have mostly personal php code, 3 wordpress sites and one joomla. I don't know a way to know which is the code who crashes.

This is a good idea, I already tried to imagine how to isolate the problem, but I don't have enough resources to separate different php sites on different servers. > 5. Can I reach you somewhere on irc in case I need to? I actually don't use irc but I can install a client on my desktop or directly under linux if it's useful. Any suggestion for the client to use?
