Just want to let you know that I've seen something similar, so I think 
there is a bug. Haven't had the opportunity to see whether it is in 
Xymon, or if it's a bug in the C-ARES DNS library handling of timeouts.

It's something I'll look into once my eyes are fully OK again, hopefully 
in a couple of weeks.
