Is this memory rising? If the below suggestion doesn't narrow down the
problem, could you look into ktrace(1) and see what it's doing all this time?
You could also try to narrow down the problem, by looking at what request was
served last by that child. Enable mod_info for that.
The only thing I see are multiple lines of these errors in error_log:
[Thu Feb 21 00:00:12 2008] [error] child process 63633 still did not

Which is correct, as the process is not exiting. For some reason it's
hanging. The old binary did not do this.
I could try another system update today (make/build/install world and
recompile the apache executable and dependencies) to see if this solves
the problem...
I doubt it would help. I've seen this lots of times when the php module exit
code is hanging. At the same time, the php CLI binary should be crashing on
exit.
Re-order your modules, there's a thread about it in the archives. If it wasn't
for that useless piece of crap ht-dig, I'd have a link for you. :p
Anyway, to test if it's this problem, run php -v and see if you get coredump.
If you don't have CLI available, you could try disabling php in apache and
see if the problem persists.
THANK YOU. I think this is definitely a good lead to where the problem
exists. I am including the output of "php -v" here.
