Apache crashing every hour - can't find the cause

I can't find the reason why Apache keeps on crashing. I have 2 http monitors and both are reporting downtimes when this happen. Fortunately it's only short, it goes back on after 3-5 minutes. On the downside, it happens at least once every hour. It's been almost two weeks since it started. During downtime, server load is normal (~1) and lots of free memory (I have 16gb on board). No significant error messages as well on /var/log/messages. Although I see notices of Graceful Reboot notices and lines containing the Apache signature saying it's running normally again. Other than that I have no clue. I'm using Cloudlinux. Apache settings: ServerLimit 2000 MaxClients 2000 MaxRequestsPerChild 10000 KeepAlive On KeepAliveTimeout 15 MaxKeepAliveRequests 150
I suspected RLimitMem and RLimitCPU as the source so I commented it, but the crashing still persists. I need advice what to do next. Thanks a lot!

  If the log is only showing that it is performing a graceful restart, then it might be restarting due to the logging. Try enabling piped logging to see if it fixes it. The option is located at: WHM " Service Configuration " Apache Configuration " Piped Log Configuration You can find our documentation on this option here:

  I suspected that too after browsing the forums. It seems it did the trick. I will monitor for 24 hours to check.
