Hmm, then I can't help you much at the minute.
Please try next time to catch a tcpdump while doing a "fs checkserv" as=20
well as catching the fstrace output. A snippet of the fileserver log=20
with a high log-level (=3D125) while doing the "fs checkserver" could be=20
helpful as well.
With this information, it might become clear why that has happened.
