Comment 2 Shehjar Tikoo 2010-06-03 10:37:39 UTC 
The server side volfiles are simple posixes+ac+locks+iot+server.

On the gl client side we have clients+afr+nfsx and three replicas under afr.

The test starts with a dd of a 1g file over the nfs mount point. When one of the replicas' glusterfsd is killed, the nfsx stops responding to IO requests. The log file and nfsx glusterfsd state dump is attached. The log shows no CHILD_DOWN and the protocol/client continuing reconnection attempts when it should not.
