I've just set up 2 diskless i586 machines with NetBSD-current
of last week.
>From time to time, they stop to respond to input, neither from the
keyboard nor from net (ICMP "ping" is still answered).
DDB shows a couple of processes (including the shells) hanging
in "nfsrcvlk".

After changing the receive socket locking code in nfs_socket.c
to the way FreeBSD handles it (don't acquire lock if the reply
is already received), the problem seems to be solved.
(At least, the box is running for half a day.)

I've never seen this with -1.2.

Has anybody similar problems?

best regards
