Unfortunately that's not the direct problem, just a clear symptom. The=20
problem is either that something is holding the desired lock and not=20
releasing it, or that nfsd keeps losing a race to aquire the lock (it's=20
released, then it's re-aquired before nfsd can get it).

I don't have any other clues for you, but the issue really involves=20
whatever is holding the lock. So the other things going on on the system=20
are important.

Oh, one quick question, does the problem resolve itself? If you leave the=
system alone, does it recover?

If not, another issue could be that you have found a deadlock issue. :-(

Take care,
