[users@httpd] Apache running with PID of 0
I am having some trouble with my installation of Apache and PHP, which had previously been running fine on FreeBSD.
I think there may be an error with my installation of PHP, but I am still trying to track that down. However, one of the symptoms is Apache ends up running with a PID of 0 (or shows up as doing so when I ps -aux | grep httpd) I don't know how to shut down this process with a PID of 0, so I am having to reboot the server every time this happens. Tried googling the problem, but not found anything useful so far.
I wonder if anyone else on the list has experienced problems like this, and knows a quick way to kill Apache when it is running as pid 0.
Cheers,
Duncan

I'll have to wait till a quiet time to get Apache into the PID 0 state -
it's a live server with customer sites on (damn!) Will post next week.
Thanks for pointing me to FreeBSD support Scott - wasn't sure if pid 0 might
be an error or not.
Cheers so far.

It sounds like php to me too, with what you've said so far.
What OS and PHP versions are you using?

RE: [users@httpd] Apache running with PID of 0

It tells me that apache isn't running and fails to start apache.
I failed to mention that this is Apache 1.3.
The problem I am having is almost certainly to do with PHP.
If I do apachectl graceful, Apache won't start up until I comment out the
Load and AddModule directives for php5 in httpd.conf.
Then if I uncomment out these directives the server starts fine.
Then running apachectl graceful again throws apache into the PID 0
situation, which I only know how to get out of by rebooting the whole
server.

What happens when you do an apachectl restart or stop?

This ("ZW") means they're all zombies (I guess freebsd shows them as
"PID 0"). Your parent httpd process seems to be spinning wildly, and not
receiving the SIGCHLDs from the children? Or something else has caused
the signals to get blocked?
I'd suspect PHP, too..

Apache now unresponsive. Apachectl stop doesn't give any changes to the
output above.
I have to reboot FreeBSD, then comment out the PHP Load and AddModule
directives, apachectl start, then uncomment those directives and apachectl
restart to get it all working again. Most odd.
Have queried the FreeBSD users list to find out about pid 0.

Can you paste the output of "ps -aux |head -1" and "ps -aux |grep
httpd" which shows this into an email back to the list?
Unless FreeBSD uses PID 0 for something unusual, having that PID would
have to be a kernel bug. Unfortunately I don't know FreeBSD that
well; maybe somebody on one of the FreeBSD mailint lists could explain
it.
