Vladimir Blagojevic commented on JGRP-959:
------------------------------------------

This issue is sometimes exhibited when channel.stopFlush() and channel#close() is called in sequence and channel is group coordinator. Thread A that invoked stopFlush() did not wait for a full completion of flush while it subsequently invoked close() which also triggered another flush (due to leave). However, this last flush immediately goes into wait-retry due to flush collision - previous flush did not finish yet. In meantime channel is torn down and a new flush triggered by close cannot finish properly - its channel does not exist any longer since it was already torn down by close().
