Hello Lewis,

You stated earlier; "NFS server is a machine running RHEL 5.9."

Did these S_rpcLib_RPC_CANTSEND problems 1st appear after switching to

the RHEL 5.9 NFS server?

What version of NFS is your RHEL 5.9 server running?

What was your NFS server before RHEL 5.9?

We had problems with corrupted saveData *.mda files at 2-ID-D that were
only resolved by upgrading to VxWorks 6.9.  We never found the root cause.

Ron

Using nfsstat on the NFS server, I can confirm that the IOC NFS client

Hi, Andrew.

Thanks for the image.  After booting with the new image, I've confirmed
the IOC NFS client is using NFSv2 now.  And 'ls' works.  Now I'll just
wait and see if the RPC problem comes up again.

Hi, Andrew.

Just following up to let you know that I have had no problems since
making this change.

It would be great if the root cause could be tracked down and fixed, or
if there was a way to easily configure whether to use NFSv2 or NFSv3, or
I'd even be fine with always using NFSv2, but I don't know if others
feel the same way.

Thanks,

Lewis
