This server is using Redhat 7.3 and Apache 1.3.26 with server-status module installed. Plesk 2.5 is installed as the control panel.

I'm wondering why Apache seems to be restarted so often (once or twice a day) by itself. I know this from the "server uptime" field in the Apache server-status page.

Is this normal? What might have caused this?

The server is in low usage and there's no user having SSH access that can restart Apache without my permission.

Thanks in advance!
