I get this:
[root at gluster03-mi glusterfs]# git fetch git://review.gluster.org/glusterfs refs/changes/28/9328/4 && git checkout FETCH_HEAD
fatal: Couldn't find remote ref refs/changes/28/9328/4
What's wrong with that?

>From the cmd log history I could see lots of volume status commands were triggered parallely. This is a known issue for 3.6 and it would cause a memory leak. http://review.gluster.org/#/c/9328/ should solve it.
