Its a known problem that Apache suddenly dies (for some), as for me. Logs shows nada, it just plain dies.
There is a simple solutions though, meanwhile this is fixed.
If you want to make sure Apache is running, you can setup a event in
/etc/cron.hourly/ (anything in here is executed every hour). You can call the
file *anything-you-like* eg. apache-restart.rc - make it by using pico and add the
following line : /etc/rc7.d/S85httpd-e-smith restart
Restart works even if apache is running or not.
I would not explain the "hard way", and remove and re-install Apache that i have done
