After months of speaking and working with Sun on this, last week they 
finally admitted there was a known problem with the system board revision,
and so sent an engineer to replace it. Since then it's been fine.

Many many thanks to those of you who responded who had seen similar

Original Description:

> We've got a Sun V880 running Solaris 9. 2 days ago it started exhibiting
> NFS trouble. We have some working and data directories mounted from
> a Solaris 8 NFS server and home directories and other working areas
> mounted from an Netapp Filer F820. The symptoms are the NFS servers appear
> to the V880 to stop responding, yet they're fine from all the other
> development machines we have accessing them, and there are no errors on
> the NFS servers themeselves. All the machines are connected by Fibre
> Optic Gig networking.
> A CVS checkout on one NFS mount causes that mountpoint, and all the others,
> to stop responding. It seems like the core NFS client stuff in Solaris 9
> throws a wobbler somewhere when we start using NFS heavily. The strange
> thing is, this has been working fine for months, and just in the past
> few days, this one machine has had nonstop NFS trouble.
> The first thing I tried, naturally, was rebooting into single user mode
> and installing the latest patch cluster for Solaris 9. This hasn't made
> any difference. Killing off the CVS command and waiting for a while for
> things to possibly recover doesn't work, all the NFS mountpoints remain
> nonfunctional - the machine has to be rebooted to get NFS working again.
> I'm going to test to see if I can trigger the symptom with just NFS IO. I've
> tried to trigger the same symptom on our other Solaris 8 and 9 boxes
> but they continue working just fine.
> Any ideas what's going on?
