non-root users take 2mins to ls a NFS dir. Root takes 7 seconds! (Sol9/NIS+/NFS/v210)

Hi there all,

I have a very strange NFS related problem.

We have a NFS server (U60) that needed to be replaced with another
system (v210).
The new system was configured in almost the same way. Difference was a
move from Sol8 to Sol9.
All patches were applied.

The (old) U60 was shutdown. No changes to it were made.
The(new) v210 had its IP address changed to the U60's and was brought
up. Nisclient was run on the client to bring it into the NIS+ network ~
A keyloign -r. The system authenicates and can decrypt the passwords.
System went live.
The exported filesystem (/stag/pe) has 48000 files in it.
Root can ls the directory from any NFS client, but for non-root users
the ls hangs for ~2mins and then returns the dir listing. A non-root
user can run ls -l freds.txt and the responce is immediate.
We rolled back to the old U60, and it now has exactly the same problem!
We have moved back to the replacement v210, which still has the problem.

Since NIS+ was the only thing that changed I wondered if this was where
I should look, although the new v210 can authenticate as far as I can tell.

Thanks, in desparation and hope!

Simon.
