[jboss-jira] [JBoss JIRA] (JGRP-1895) FLUSH_NOT_COMPLETED race condition

[Dennis Reed (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13015436#comment-13015436 ] 

Dennis Reed commented on JGRP-1895:
-----------------------------------

Possible fix for the specific issue in my previous comment:

When handling FLUSH_NOT_COMPLETED, if flushCompleted is true (which will never be the case if
the FLUSH_NOT_COMPLETED is for the current flush), then just ignore it.

> FLUSH_NOT_COMPLETED does not keep track of which FLUSH it was related to.  FLUSH_COMPLETED only keeps track of whether the FLUSH was for the current view.
> If these responses are delayed (which can be caused by a long GC pause on the node sending it) where a new FLUSH has been started, these can be interpreted as responses for the wrong FLUSH.
