We recently had a major change in our network's design. The entire topology had the change, including IP addresses of servers and the "routes" through switches between things. Ever since then, Xymon is reporting very brief (10-20 seconds) outages of one server or another every 30-60 minutes.
I tried this suggestion: http://xymon.sourceforge.net/docs/known-issues.html#netfail
No luck. A few minutes later, the server Xymon is running on allegedly failed the "conn" test for about 1 second.
Any other ideas? If you want to see the symptoms, look at my Xymon instance at http://cns.cairodurham.org/hobbit/bb2.html. This will show the brief outages that I'm talking about.
Thanks in advance, Jaime Kikpole
