Dear list,
My setup have 1 master and 1 slave. Everything seems ok, but
sometimes I got CRITICAL on slave check with message: "NSCA problem
- status code: 2 - restarting tunnel". After about twenty minutes it
recover to OK. It occurred randomly and I really don't know what
happen. No crash, no log, it simple down and up again.
I've read from opsview site that we'll lost any result before it
recovered so I wonder anyone have any idea about this problems.
We've seen something where ssh timeouts cause the tunnel to shut down.
The check then comes along to restart the tunnel on the master.
This is hard to investigate without seeing your system, but that's
where to start.
