Bela Ban commented on JGRP-2237:
--------------------------------

So if we look at the view changes, the following happens: {{654}} is the first member, then {{11729}} joins. Next, {{654}} (the coord) leaves. Then, {{28153}} joins, but becomes singleton as it doesn't get a discovery response from {{11729}}.

This could be because of a misconfig; again. I tried my {{test.xml}} with {{master}} at least 30 times, and it always worked, and views were created correctly.

> When the first one is rejoin, he could not determine coordinator and select new one from the nodes list.
