[jboss-jira] [JBoss JIRA] (JGRP-1743) NAKACK*: log a warning if xmit_table gets large

[Dennis Reed (JIRA)]

     [ https://issues.jboss.org/browse/JGRP-1743?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dennis Reed updated JGRP-1743:
------------------------------

             Affects Version/s: 3.4.1
                      Priority: Minor  (was: Major)
                   Description: 
There have been some cases where NAKACK* accumulates large number of messages, causing OutOfMemoryErrors.

Large numbers of messages in NAKACK* would almost always indicate a problem, which the user should be aware of.

Logging a warning if the number of messages in NAKACK passes a configurable threshold would let the user investigate and take action sooner before a catastrophic OutOfMemoryError, or other issues occur.
