httpd dying

Once every few weeks my apache process dies and won’t restart (when I do an /etc/init.d/httpd start it fails and says “unable to open log files”). I haven’t opened a ticket yet because rebooting the whole box “solves” the problem, but I’d obviously like to stop having apache die semi-randomly on me. Any ideas on why this is occurring?

My apache has been failing to restart since the first 1.9 update. It reset itself when the log scanning runs, but 4-5 days out of a week it fails to start back up.

Doing an service httpd restart fixes the problem. I don’t have to reboot my server.
