Problem: It was observed that in some cases client disconnects and re-connects before server xlator could detect that a disconnect happened. So it still uses previous fdtable and ltable. But it can so happen that in between disconnect and re-connect an 'unlock' fop may fail because the fds are marked 'bad' in client xlator upon disconnect. Due to this stale locks remain on the brick which lead to hangs/self-heals not happening etc. For the exact bug RCA please look at https://bugzilla.redhat.com/show_bug.cgi?id=1049932#c0 Fix: When lk-heal is not enabled make sure connection-id is different for every setvolume. This will make sure that a previous connection's resources are not re-used in server xlator.
