Daily Crash

Hi all,

I have a cPanel instance that seems to randomly crash and not re-start when the stats collection is performed on the 2 hour schedule.
I've not been able to figure out the exact cause however when it crashes the apache error_log indicates:

Code:

As you can see exactly at the 2 hour interval the graceful restart happens then it crashes.
To work around the issue for now I've enabled piped logging so that the restarts don't happen but I was wondering if anyone could perhaps advise why this seems to be happening?

I've tried endless searching but still no solid answers.
