I have an annoying problem that (so it seems to me) started after we
upgraded two of our NeXTs to 3.0 and started using one of them as an
NFS server.

In random intervals (approx 1/day) all the machines in our little network
(2 NeXTs running 2.1, one of them serving /Users and /usr/spool/mail,
2 NeXTs running 3.0, one of them serving /LocalApps and /usr/local) will
hang with the 'NFS server xxx not responding' message. Sometimes the
problem goes away, sometimes you have to reboot the servers, sometimes
one of the machines will panic. I found the following in /usr/adm/messages
(ruble/mailhost/128.130.167.130 is the 2.1 server, moolah is the 3.0 server):

Nov 20 13:31:25 moolah mach: NFS server ruble not responding still trying
Nov 20 13:31:29 moolah mach: nfs_server: bad sendreply from 128.130.167.130
Nov 20 13:31:36 moolah last message repeated 2 times
Nov 20 13:31:42 moolah mach: NFS server mailhost not responding still trying
Nov 20 13:31:44 moolah mach: nfs_server: bad sendreply from 128.130.167.130
Nov 20 13:32:02 moolah mach: nfs_server: bad sendreply from 128.130.167.130
Nov 20 13:33:42 moolah last message repeated 9 times

The panic happened here (said something about ns_timeout table overflow).

Nov 20 13:33:57 moolah syslogd: going down on signal 15
Nov 20 13:34:51 moolah mach: Killing all processes NFS server ruble ok
Nov 20 13:34:51 moolah mach:

Nov 20 13:34:51 moolah last message repeated 4 times
Nov 20 13:34:51 moolah mach: unmounting /Users ... done

Nov 20 13:34:51 moolah mach: unmounting / ... done

Does anybody have a hint what could be causing this?? It really starts to
get annoying, and I have not the slightest idea what we did wrong.
