BTW, I don't know if this is a related or a separate problem,
but I get a _lot_ of these on server log both from Linux and Mac OS X:

Nov 25 22:26:43 server rpc.lockd: no matching entry for core7
Nov 25 22:26:44 server rpc.lockd: duplicate lock from core7.27

I know that question has been asked at least one and a half years
ago but I haven't yet found an answer.
