Hi,

I have a Linux box as an NFS server and a FreeBSD box which acts as an
NFS client. If I explicitly shutdown the NFS services in the Linux box,
actions like 'df', 'ls /mnt' (/mnt is the mount point of the remote
directory), or even 'umount /mnt', in the FreeBSD box, seem to lock forever.
I waited for about 20-25 mins, I got a 'server not responding' message, but
the processes were still locked and I could not even kill them.

I started again the NFS services in the Linux box and I got a 'server alive'
message in the FreeBSD box, after about 10 mins. 

Is that the correct behaviour? I had a look over /sys/nfs/nfs.h and the
configuration constants seem perfectly resonable. I would like to help 
solving the problem, if it is an actual one. Otherwise, my apologies for
taking your time.

FreeBSD box:
FreeBSD gluon.particles.org 5.0-20000406-CURRENT FreeBSD 5.0-20000406-CURRENT #0: 
Thu Apr  6 13:52:15 GMT 2000     root@usw2.freebsd.org:/usr/src/sys/compile/GENERIC  
i386

Regards,
Elias
