Apache won't restart

Virtualmin Theme version: 6.4
Virtualmin version: 3.63
Operating system: Redhat Enterprise Linux 4ES
Apache abruptly stopped a couple hours ago. I got an email notification and immediately logged in. It will not restart, and there is nothing in the log file.

I have tried rebooting the server with no luck. Also, have had a friend looking at it for an hour and he cannot figure out what the problem is either.

Last time I had this, I ran the command "ipcs -s | grep apache | perl -e 'while () {@a=split(/\s+/); print `ipcrm sem $a[1]`}'"

My friend says he ran this, and still nothing. Starting apache from the command line just quits, but does not produce an error file.
