Hi all,
I'm experiencing problems with a 4.9 server attached to a NetApp. Some
background. There are several Solaris 8 machines connected to it, and
(2) FreeBSD 4.9 machines. The Solaris servers and one FreeBSD machine
have no issues connecting to the NetApp. However, the 4.9 server in
question does. It was configured identically to its' sister 4.9 server.
The NetApp in question acts as a mailstore.
Specifically, the problem occurs when our MTA attempts to deliver a
message to the mailstore. The spawned process hangs, and this message
occurs in /var/log/messages.

not responding
Let me re-iterate that the problem only occurs on the one machine, and
it is configured identically to the other FreeBSD server. Here is the
appropriate snippet of the /etc/fstab file:
192.168.1.10:/vol/web0 /remote/web0 nfs
rw,-r=32767,-w=32767,dumbtimer,intr,nfsv3 - -
I have tried udp and nfsv2 to no avail. To debug this I have been using
tcpdump and nfsstat, but because the problem is unpredictable, I haven't
been able to see the issue occur.
Can anyone suggest something? Either a potential cause or another way
to determine the cause..
