Hi list

I trapped into an apache2 freeze thing (debian sarge, apache2
libapache2-mod-php4)

After certain time (from few minutes to many hours) apache simply
freezes. Freeze meaning here: Processes still present but no
processing time on them. Each request is not responded but queued
(showing status bar till timeout).

When i restart apache2 anything is fine again - at least for some
minutes.

Trying to trace it down to some buggy script execution i checked
logs and found nothing similar between those events.
This is a live installation and we're suffering... System load at
~1.0 .. 2.0
The issue started at one specific day, where we didn't change
anything by intention. Replacing the whole hardware also didn't
help.

Is there someone to show me ways to debug this issue or any idea?!

(Personal contacts also apreciated.)
I'm happy to hear any input about this one.

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. ;-)
