Apache restarting every hour

[kenzie]

My httpd died earlier today, so I went looking through my error_log to find out why, and noticed that Apache is being restarted every hour. Is this normal?

It is -HUP signal sent for bandwidth logs not restart. Remove the file dsm-bwcheck in /etc/cron.hourly. I think that they taking it out of Lite version anyways. A answer posted to someone else asking already, but i can't find it.
