Unsure if this is a bug or not. I noticed that for a few days I've been getting "Runtime 483 longer than time limit (300)" and the bbtest column shows:
TIME SPENT <snip> DNS tests executed 450.074868 <snip> TIME TOTAL 482.741716
I was able to successfully debug this by adding "--debug" to the [bbnet] CMD in hobbitlaunch.cfg. This revealed:
2009-09-01 08:26:01 ares_search: tlookup='dns.server.com', class=1, type=1 2009-09-01 08:26:01 Processing 0 DNS lookups with ARES 2009-09-01 08:33:31 Finished ARES queue after loop 20
Note that it took 7 minutes to complete this. Where 'dns.server.com' is a server that we took offline on the day the issue began. We didn't remove this from bb-hosts and instead marked it blue.
The fix was to comment it out from bb-hosts. It says "loop 20" above so I was searching for config options that listed 20 as a value but didn't come up with anything.
The issue is resolved on my end but I'd like to find out if this is a bug or expected behavior. It seems that a single DNS check on a host that's down shouldn't delay things by 7 minutes.
I'm running Xymon v4.2.3 on FreeBSD 7.2-RELEASE.
Thanks, Chris
