Created replicate volume with replica count.

2 fuse clients, 1 nfs client.

1 fuse client executing sanity script, nfs client executing the sanity script and the other fuse client executing iozone.

Added 2 more bricks to the volume thus making it 2x2 distributed replicate setup. enabled quota and profile.

nfs client hung.

Triggered the self-heal by bringing a brick down and up.

This is the statedump.

statedump indicates lot of pending frames from replicate. Pranith can you take a look? Assign it back to me in case it is an NFS bug.
