Comment 1 Amar Tumballi 2011-12-20 05:29:32 UTC

This issue seems to be NFS's File Handle resolution for depth more than 16.. Should be fixed after the GFID based patches go-in.

Comment 2 Amar Tumballi 2012-01-25 05:37:10 UTC

With patch http://review.gluster.com/2645 this should be fixed.

Verified on 3.3.0qa42, no such message appears
