Anyone encountered the same issue like this?

Apache will just restart after several minute or idle time.

Here’s the logs.

Hello, @Menj

Can you please check the /var/log/messages for any killed processes? The apache process may be killed if it’s using a lot of resources. You can check this using the following command:

grep -i kill /var/log/messages

You can then check if there are any references for apache as well or you can modify the command to show those related with apache:

grep -i kill /var/log/messages | grep apache

Let me know how it goes.
Alex
