I installed the 6.4 release on a test desktop and the newest nfs4
packages did not fix the issue regarding the lock reclaim failure.

Has anyone experienced the same (or a similar) problem with NFS4 on SL6
clients starting from the 2.6.32-279.22.1.el6.x86_64 kernel up to the
current one?

Suggestions?
