httpd failed (weird pid file)
Hi,
This is my first post to this group.
Apache 1.3.19-5 was running fine on RH7.1 machine. But
from yesterday it failed to start. There is no error
on the error_log file. In the /var/run it shows as
httpd.mm.xxxx.sem where xxxx=number which i believe is
the pid.
Searching through google i found a bit which says 'mm'
relates to shared memory. But didn't help me much.
Can anyone please help me what is wrong?
Thanks.

If it had reached the point in the startup where the error log was available,
you'll find messages in there. Errors that occur before that point go to
stderr.

thanks a lot Mark,
i will delete the mm...sem file everytime i shutdown
the server and one more thing, if the httpd fails to
start where does it write error messages (logs) 'cos
previously i faced this a major problem. though the
server started without me making any changes, except
log level to debug, i want to be prepared for next
time.

If the server is running, and the messages below are all you see in your error
log, you shouldn't worry. Everything looks normal, including the
httpd.mm.#.sem file. That file should be removed as part of a normal shutdown,
its presence is not an indication of a forthcoming crash.

You invoke httpd with -X directly, not through a script. Make sure Apache
isn't running, find out how httpd is started in init.d, add -X, and type that
command into a shell as super-user.

Thanks Mark,
The apache server started ok with pid 7150 but it also
created httpd.mm.7149.sem in /var/run. With loglevel
'debug' it gave the following in error_log. I think
running this way will again cause the server to fail.
Though it is not a production server but is only for
inhouse s/w development with php and mysql, it is
still worrying me.
Can you guide me more?
And how do i start httpd with -X option. i tried from
/etc/rc.d/init.d but it does not take any option only
start,restart etc.
Thanks again

httpd.mm.#.sem is used as a semaphore for certain shared memory
operations when using a version of Apache built with the extended API
and common configurations of the MM library. EAPI is added to Apache
in order to support mod_ssl.
Sometimes, Apache will exit in such a way that this file (and
potentially other files) will not be cleaned up. They're safe to
remove, but their presence alone doesn't tell you much specifically
about why Apache is exiting or refusing to start.
Apache may be exiting before it has an error log available. Does it
print anything to stderr when you attempt to start it yourself? It's
also possible that you have an inappropriate ErrorLog or LogLevel
setting in your configuration file, try "LogLevel info" or possibly
even "debug". You might also consider starting httpd with the -X
argument in addition to the arguments that you normally use; this will
cause debugging messages to be printed on stderr and will prevent the
server from forking.
