Apache httpd SIGTERM Every 5 Minutes on VPS

[viebig]

Hello, I really need some help...

I´m running a video website, apache restart every 5 minutes, at the first second. Tried to recompile apache and php several different ways, same result.

Statistics software update every 24 hours.

Apache error log:

I'd suggest you check cron logs and /var/log/messages for any oom or related resource shortage errors and /proc/user_beancounters if its a Virtuozzo based VPS. If its getting killed after an exact number of minutes, its probably a cron that is causing this.
