Hi there,
I'm seeing a curious problem with my NFS mounted home directory...
Every now and again, it just hangs, in the usual NFS fashion with a
message:
Oct 25 14:28:09 voodoo /kernel: nfs server admin:/export/home: not responding
% grep /home /etc/fstab
admin:/export/home /home nfs rw,-i,-3,-T 0 0
% uname -a
FreeBSD voodoo.pandhm.co.uk 2.2.8-RELEASE FreeBSD 2.2.8-RELEASE #0: Mon Nov 30 05:15:30 GMT 1998 root@voodoo.pandhm.co.uk:/usr/src/sys/compile/VOODOO i386
% ifconfig xl0
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.100.35.12 netmask 0xffff0000 broadcast 10.100.255.255

It's running on a 100BaseT switched network to a Solaris 2.6 server.
The funny thing is that when it hangs, it doesn't recover, the way that
I have seen before with these problems. What is even weirder (to me) is
that I can mount the problem filesystem in a different place (say, /mnt)
and it works fine! The underlying network connectivity isn't going
away. BTW, I've also started using the access cache which has just
recently been imported. It seems to work great (aside from this slight
problem, but I'm not sure if it's related).
I realise that this isn't enough to go on for solving the problem. What
other things can I try when the /home mount gets hung again? Can I
force a crash dump to take a closer look?
Thanks for any assistance.
