I'm not sure what you mean by a "lost" mount. Do all further accesses
to the filesystem hang?

It is normal enough to get the above 'not responding' errors
occasionally on a busy fileserver, but only if they are almost
immediately followed by 'is alive again' messages.

If the filesystem stops working and doesn't recover, could you run
`tcpdump -nepX -s 1600 udp port 2049' when it hangs and record a
few packets?
