FastCGI causing 500 Errors

[rootzwiki]

Hello,

In the past few days we've been experiencing issues with fCGI, it appears sporadically but can always be triggered by trying to do a password reset. For example, if I were to try and get my password reset, enter my email, and try to send them, it will time out and pass me to the internal server error page, but then in a few minutes I get my login details.

checking the apache error log:

I've spent the past day re configuring everything, recompiled apache and php multiple times, all to no avail. We're running vBulletin 4.1.3 Patch Level 3 and only running a few plugins like tapatalk, forum runner, etc. In the past few day's we haven't installed much that would interfere, and while troubleshooting I removed some software installed in the past few days.

I'm sure you'll want more info about our system, let me know what else I can provide.

Appreciate any and all help
