Chris Nauroth updated HADOOP-11604:

         Summary: Prevent ConcurrentModificationException while closing domain sockets during
shutdown of DomainSocketWatcher thread.  (was: Reach xceiver limit once the watcherThread

one particular bug, perhaps different from the original reported issue's root cause.
