This looks remarkably like the error we were experiencing.
What are you running on?

Do you have the case where all the network tests - ping, http, https, ftp
etc. go purple?
If so it might be the same.

With Henrik's assistance, we resolved it down to a problem with the ARES
resolver.
I changed our hobbitlaunch.cfg file to include the --no-ares option (see
below), and we have never had the issue again.
[bbnet]
        ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD bbtest-net --report --ping --checkresponse --no-ares
        LOGFILE $BBSERVERLOGS/bb-network.log
        INTERVAL 5m 
(Of course this does come with a caveat. See bbtest-net man page in Xymon
docs http://www.xymon.com/hobbit/help/manpages/man1/bbtest-net.1.html )

YMMV.

Cheers

This night, after installing the new bbtest-net, we received an alarm on bbtest for the Xymon server, saying " - Program crashed Fatal signal caught!"
From hobbitlaunch.log: "2009-01-08 05:05:07 Task bbnet terminated by 
signal 6"
/Johan


If the program crash, you should have a coredump. Run gdb on the coredump
and post the result here, for Henrik to look at.

Hi,

I had purple on all the net tests (ping,http, https...)
Your solution to use the --no-ares option is with the recompiled bbtest-net
or with the original one ? (in fact , your solution fix the DNS test
problem, or the massive purples one ?)
