[client.c:2227:client_rpc_notify] 0-patchy-client-1: disconnected from
patchy-client-1. Client process will keep trying to connect to glusterd until
brick's port is available   <---------------- The brick went down at this
point.

[dht-common.c:10557:dht_notify] 0-patchy-dht: Received CHILD_DOWN. Exiting


As Nithya pointed out, rebalacne won't continue if the brick is down and will
terminate.  If there is a crash on the brick side, can you attach the core or
more preferably backtrace from gdb?
