Runtime longer than time limit (300)

[Chris Wopat <chrisw (at) supranet.net>]

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
