[Dan Berindei (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-8431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13578330#comment-13578330 ] 

Dan Berindei commented on ISPN-8431:
------------------------------------

It seems much easier to reproduce if I added a random delay before updating the topology in {{StateConsumerImpl}}. To be fair I was testing ISPN-7682 my changes, replacing all uses of {{StateConsumerImpl}}'s topology with the {{DistributionManager}} topology, so I was only delaying the {{DistributionManagerImpl.setCacheTopology()}} call.
