Hi Trond!

I'm seeing _a_lot_ of those messages on one of my
test servers (probably caused by a client doing an
rsync -aX to an nfs mount), so I added a rate limit
and a stack trace which results in those traces:

(0x37270000 looks strange for an errno)

Any ideas how to fix that properly?

Thanks in Advance,
Herbert
