Apache service stop automatically in coral_8_5_4

Two days ago I installed coral 8.5.4 version and everything was fine but after 2 hours Apache service stops.

I manually restart the service but after some time it again stopped.

Then I try Coral_8_5_2 but it also producing same errors. Below are full details of error.
