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.
