I've got a Solaris 10 u4 x86 machine with a vexing issue. It's an NFS
client of a v240 running Sol9. It works fine for a few weeks, and then
seemingly at random, begins to lose contact with the NFS server.
Mount requests, file open/write requests are issued by the client, are
picked up by the server and are responded to. The network acks make it
back to the client's NIC (I've got the client hooked to a hub w/ a
laptop connected via same in promiscuous mode), but snoop on the
client doesn't show the NFS traffic that I see on the laptop. All
other network traffic goes through fine. These are hard NFSv3 mounts
over TCP.
Why have you used UDP? Can you show us the mount commands you've used?
For example, one of the affected filesystems is mounted read-write, background enabled, nosuid and quotas on. UDP was the lowest-common-denominator transport for lots of clients, but this one could just as easily be switched to TCP.
