Ah then, I believe the fix for this issue is part of 144489-10(kernel patch),
related to CR BUGID 6976554, I could be wrong, we will reboot 1 of our servers
with that on Thursday. (All others run IDR fix).

Hi Jorgen,
Thanks for the info.
It looks like this is my problem. I've seen the OpenOwner climb over 1 million,
then I get NFS4ERR_STALE_CLIENTID errors.
In your earlier post, you said:
We can unmount/remount to free many locks, and about every 20 days, we
do maintenances where we restart nfsd.
I tried re-sharing just by doing a 'zfs set sharenfs=on pool/filesystem', but
the locks kept increasing.
I restarted the nfs/server and the locks went down to zero.
The Nagios idea is good as well. I like graphs.
Regards
John

I don't know anything specifically about your issue, nor do I work for Oracle,
but you could check to see if it is related to the trouble I was having:
http://opensolaris.org/jive/thread.jspa?threadID=118755
In particular, run the mdb command to see if you are also running out of
OpenOwner locks.

I see a lot of views, but no ideas?
I've reproduced this on another box, completely different hardware, but same OS.
I run around 16 simultaneous reads from 12 different clients, and after some
time I get the same symptom.
Restarting nfs/server helped the first time I had this problem, but now it
doesn't.
I've tried to do an svcadm restart nfs/server but for the last 30 minutes I still see the
process "/sbin/sh /lib/svc/method/nfs-server stop 93"
Looks like I have to reboot.
Regards
John
