I'd say that there is a definite leak somewhere. The question is where.
I'll run some buildworld tests w/ the latest current to see if I can
cause mbufs to leak. I suspect that the problem may be related to a
specific situation, though, such as a particular type of FS op failure.
Unfortunately, I do not have any -stable machines setup at the moment
that I can use for NFS testing.
You could try backing out the nfs_serv.c and related patches from your
-stable source to see if that fixes this particular problem. If it does
then we will know where to look.

:Ok, here are some real stats....
:
:"w" is the read-only machine, it services everything that "s" (the
:read-write machine) does... in fact it services more.
