Signal 4 is "illegal instruction", it might be caused by:

- corrupted executables
- executables built for processor architectures different than the one
used in the machine (e.g. built on one machine with CPU optimizations
turned on, then run on another)

Do you have any processor-specific instructions in your make.conf? How
did you install apache and other applications? Have you tried
recompiling apache and php without any optimizations?

Are you using PHP as mod_php? If so, you might want to try to switch to
fastcgi to isolate if the problem is in apache or php.
