Hi all,
I am running version 4.1.2p1 of Hobbit on SuSE Enterprise Linux 9 SP2 X86_64. It is unpredictable on when it is going to crash. It runs for days with no problem then crashes every five minutes for an hour then may for days again before it crashes. Is there a fix for this and I just missed it when looking through the archives?? The gdb output is below:

Looks suspiciously much like a known bug in the C-ARES library that Hobbit uses. The workaround is to run bbtest-net with the "--no-ares" option.

Henrik,
I am running with the --no-ares option and getting this.
Core was generated by `/etc/local/hobbit/server/bin/bbtest-net "--ping" "--checkresponse" "--no-ares"'.

Sorry, I should have checked that first.
In that case the ARES lookups are caused by some of the DNS tests you have (they will always use the ARES library). Do you have any special dns checks ? Or just the standard "dns" entry in your bb-hosts file ?
Regards, Henrik
Just the standard entry in bb-hosts.
