Description Bernd Kuhlen 2008-01-17 22:10:09 UTC

After Upgrade to FreeBSD6.3 my nagios daemon startet to hang. So Service checks were not performed anymore. For some reason the parten forked service processes with a WCPU of 100% taking all the cpu. 

The only workaround was to kill -9 the corresponding pid. This is not of much help since Nagios doesn't repeat killed service checks anymore (or I don't now how). So  
I had to combine a cron script killing these processes (to give you an idea: were are performing about 1000 service checks per 15 minutes. Roughly 10 of which were malfunctioning) and I had to reload the nagios-daemon in order to reschedule killed service checks.

Fix: 

I downgraded to 
6.2-RELEASE-p10 FreeBSD 6.2-RELEASE-p10 #0: Thu Jan 17 20:21:26 GMT 2008 

Now everything is working fine again.
How-To-Repeat: I tried Nagios 2.10 on FreeBSD6.3 PRERELEASE amd64

I'll take this one.  It's related to ports/119246 which I almost have ready for commit.

[ Resending, because I fat-fingered an address the first time. ]

Jarrod,

ports/119766 was recently submitted.  This appears to be the same
problem with ports/119246.  Just wanted to make you aware of this new PR
which I will be keeping open.

My understanding is that you plan to backport the fix for nagios-devel
after appropriate time.  If that's the case then Bernd can use the
suggested libmap.conf workaround until you feel comfortable updating
net-mgmt/nagios.

Wesley,

I have raised ports/120150 to resolve the process hanging issues with  
net-mgmt/nagios.  No negative feedback has been received from the same  
patch for net-mgmt/nagios-devel and all tests confirm libpthread()  
isn't used.  Feel free to grab it and do your thing...

Jarrod.
