ZoneMinder Forums

I read this in the README:
If you find you have several zms processes running when nothing is being viewed then it is likely you need a patch for apache (see the Troubleshooting section).

The troubleshooting section did not mention anything about a patch for apache. I also cannot find anything addressing this in the wiki or in these forums.

I am running an rpm apache2-2.0.47-6.12.92mdk.i586.rpm (Mandrake 9.2 w/patch) And I built ZoneMinder v1.22.2 from the source.

Almost everything else works fine (thanks for the great software), I am just curious how to stop all these zms processes from getting wedged, as it slows my entire server to a crawl after a while.

They take CPU and memory even when the browser that connected to them has long since been closed.

Update your apache package to 2.0.48. That should take care of your problem.

Thanks -- unfortunantly, I'm having a bit of a hassle finding a 2.0.48 rpm version of apache for Mandrake 9.x that is not compiled as a threaded MPM (threaded MPMs seem to be conflicting with PHP) I should just build apache (or a whole machine) from source, or upgrade to a newer distro. It's been a few years...

FWIW, I wrote a little script that I put in my crontab to run once per minute that kills all but the last 3 nph-zsm processes based on PID. This keeps my server from getting bogged down for now until I get apache upgraded.

ps ax | grep nph-zms | tac | awk 'NR>4{ print $1 | "xargs kill -9" }'

I'm seeing this behaviour using apache 2.0.55 (specifically 2.0.55-4ubuntu2). I built ZM 1.22.2 from source as well.

Gotta love a load average of 16.5

It eventually cleans up by itself (taking about 10 minutes).

Ah, the "sorry, no idea" silence . . .

I went to the old FAQ, and both links (to the patched RPM and the forum discussion) don't work.

Can anyone point me to the original apache bug info so I can track down that it's really in Ubuntu's release?

i'm running ubuntu 6.06 with apache 2.0.55 on 3 machines. I saw a bit of a problem with high loads until i upped the shared memory, but i haven't been seeing any particular problem with nph-zms processes hanging around after the client closes. these machines are intel boxes (1.5 ghz and up), 1 gig memory with nothing else difficult going on in them.

no idea really whats going on but just a data point for saying there aren't any problems here in that regard.

Thanks for that. It sounds like my HW is similar (Celeron 2GHz, 1G memory)

Did you build ffom source?
What did you set the shared memory to?

Thanks again.
