NFS Locking Problem - Continued

Hello again,

Still no luck with getting a Tru64 5.1 client to 'vi' a NFS'ed share from
another 5.1 server.

These tests are done by modifying (using vi) a text file that's about 15
bytes in size.

With a NFS Server 5.1 ECO#5:
*) 5.1 ECO#5 client, vi fails, ctrl-c will interrupt
*) 5.1 ECO#0 client, vi fails, ctrl-c will interrupt
*) 4.0F ECO#4 client, vi succeeds!

NFS Server 4.0F ECO#4:
*) Client 5.1 ECO#5 vi succeeds (although, another 5.1 client failed and
locked the process)

Other points of consideration:
* In all conditions, using 'ed' to modify instead of 'vi' works fine
* creating a new file using vi works. Locking only affects existing files
* netstat -i shows a 1 in 360,000 Out Packet error ratio
* no difference was seen using either TCP or UDP as the protocol
* name resolution is via a distributed hosts file

Me thinks it's time to log a support call if there are no other suggestions
from you good folk.

Damien.

Subject: NFS Locking Problem

Hello all,

I have one NFS server and 6 NFS clients. All are running Tru64 5.1 with
patch kit 5.

One system gets stuck when trying to access files over the NFS share and
/var/adm/messages comes up with "NFS3 server .... not responding still
trying". Doing basic cd and ls listings are fine, but vi fails. So this
must be a locking problem of some sort. By turning locking off the nfs
client, I can then vi the files but some other process is still making the
share report the "not responding" message.

Looking through the managers list I see that other people have had similar
problems as well. Unless my searching has let me down, no summaries have
been posted.

Help! :-)

Thanks,
Damien.
