It didn't panic yet, but when doing a multiple simultaneous cvs update
with NFS3 mounted repo the clients eventually got stuck in the nfsreq
state.

FreeBSD had a similar problem for a while, after a change made last
December, but it was fixed early this year.  Is your server based on
an old version of the freebsd server code that is missing this (and
possibly other) fixes, or is this a new bug introduced in your
version?
