Usual things to check when Apache segfaulting.

1. Check server RAM.
2. Don't run self compilled software or software which comes from 3rd party repositories and extensivelly uses other original software on the machine. For example don't run 3rd party PHP RPMs with original Apache.
3. Try to completely uninstall PHP extensions and pecl modules one by one.
4. Try to disable Apache modules one by one.
