             Summary: Don't log an IllegalArgumentException when receiving an invalid delta view
                 Key: JGRP-2421
                 URL: https://issues.jboss.org/browse/JGRP-2421
             Project: JGroups
          Issue Type: Enhancement
    Affects Versions: 4.1.6
            Reporter: Dan Berindei
            Assignee: Bela Ban


When the cluster is unstable but not because of the network (e.g. excessive load and long GC pauses), a suspected node can keep receiving view updates long after it was excluded from the view. 

The first view triggers a warning about not being a member, but because later delta-views cannot be reconstructed, their warnings look much worse, even though they're about the same thing.

Maybe GMS could keep track of when it receives a view in which it is not a member and stop processing delta views from that node?
