I had the same problem on a machine with a new Etch install of
Apache 2 and PHP5. For a week I struggled with the problem and it
finally came down to the php5-clamav module while already running
clamav on the machine. Since you're running PHP4 though, I don't
know.
For my problem, there was nothing I could find in any of the logs,
and Apache would freeze at varying minutes/hours after it had been
restarted. I removed Apache modules but the problem persisted. I
ran memtest86+ on my memory modules, but the problem persisted. And
Google was not my friend. Finally, since I'd tested everything in
the machine and I'd removed all unnecessary Apache modules, to no
avail, I started on PHP modules that weren't critical. That's how I
found my problem.
I'm sorry not to be much help, but I wish you luck. ;-)
