This was previously posed to the sun-managers mailing list but the only reply I received recommended I post at zfs-discuss. The only reply I received there recommended I post here. This is my last mailing list for this issue I swear.
We have a production Solaris 10u5 / ZFS X4500 file server which is reporting NLM_DENIED_NOLOCKS immediately for any nfs locking request. The lockd does not appear to be busy so is it possible we have hit some sort of limit on the number of files that can be locked? Are there any items to check before restarting lockd / statd. This appears to have at least temporarily cleared up the issue. Thanks, Chris
