Hello, @SP1

When this happens have you checked if the Apache service goes down? What you can do is to examine the logs for killed processes and also out of memory entries. To check this you can run the following commands:

  1. grep -i kill /var/log/messages
  1. grep -i `oom` /var/log/mesaages

Hope that this helps! Regards, Alex

what thats mean?
