I would suggest the next time it happens get a netmon trace for what netmon
is doing. When you ping from the map, netmon is the application that traces
the ICMP request.  Determine if netmon is actually sending the ping.
 "netmon -M 3" from the commandline will activate tracing of ICMP request
and replys.   Examine /usr/OV/log/netmon.trace to determine if the request
is actually being made.

What version are you at please?

Recently our network operators reported a very similar thing
happening.  They were certain an interface was up but netview
couldn't ping it.  I wasnt present so I was very much baffled
by their claims.

Have you tried to reproduce the problem?  If it is reproducible
it could be a bonafide bug.
