Subject Re: [users@httpd] Apache eventually stops responding?
Date Wed, 27 Oct 2004 18:25:01 GMT
Thanks for the reply, Joshua! FYI here is what I see in my log. If you
look at the times, there is nothing betwen 8:48 and 8:59. Typically, I am
getting a couple of error messages every minute about files not being
found, so after 8:48 must be when http stopped responding... I assume the
subsequent warnings are because of my manual "apachectl restart".

[Wed Oct 27 08:48:08 2004] [error] [client 200.244.52.33] File does not
exist: /var/www/...
[Wed Oct 27 08:48:19 2004] [error] [client 206.64.195.253] File does not
exist: /var/www/...
[Wed Oct 27 08:59:39 2004] [warn] child process 5723 did not exit, sending
another SIGHUP
[Wed Oct 27 08:59:42 2004] [warn] child process 5723 still did not exit,
sending a SIGTERM
[Wed Oct 27 08:59:47 2004] [error] child process 5723 still did not exit,
sending a SIGKILL
[Wed Oct 27 08:59:48 2004] [notice] SIGHUP received.  Attempting to restart
[Wed Oct 27 08:59:49 2004] [warn] module php4_module is already loaded,
skipping
[Wed Oct 27 08:59:49 2004] [notice] Apache/1.3.27 (Unix)  (Red-Hat/Linux)
mod_ssl/2.8.12 OpenSSL/0.9.6b DAV/1.0.3 PHP/4.3.2 mod_perl/1.26 configured

[Wed Oct 27 08:59:49 2004] [notice] suEXEC mechanism enabled (wrapper:
/usr/sbin/suexec)
[Wed Oct 27 08:59:49 2004] [notice] Accept mutex: sysvsem (Default: sysvsem)

How do I go about diagnosing this further? I'm not that fluent in linux. I
did a "top" and saw that I didn't have any high loads when apache wasn't
responding, but I don't really know what other commands I should be using
to check the server status.

Thanks again for any help!
