Neal Dillman commented on JGRP-2092:
------------------------------------

That is correct -- the issue was only seen during merges.  It is exacerbated with a significant quantity of hosts across bandwidth limited routed network.  More specifically, if there are hosts on a 1G network that are connected by lower bandwidth lines -- like 256k.
