[jboss-jira] [JBoss JIRA] (JGRP-2387) Message from a non-member causes FD_ALL to continually suspect it
[

Bela Ban commented on JGRP-2387:
--------------------------------
Workaround to make the warnings go away:
* Set VERIFY_SUSPECT.use_icmp to true
* Remove VERIFY_SUSPECT
* Increase UDP.who_has_cache_timeout (this should reduce the frequency of the warnings,
but not completely eliminate them)
I haven't tried these, but perhaps it's worth experimenting with these workaround
until I have a fix?
Message from a non-member causes FD_ALL to continually suspect it
-----------------------------------------------------------------
Key: JGRP-2387
URL: https://issues.jboss.org/browse/JGRP-2387
Project: JGroups
Issue Type: Bug
Affects Versions: 4.0.1
Reporter: Dennis Reed
Assignee: Bela Ban
Priority: Major
Fix For: 4.1.6
Attachments: Test.java
If an FD_ALL control message from a non-member is seen by FD_ALL, it will start
continually suspecting that node. If msg_counts_as_heartbeat=true then any message from a
non-member triggers the issue. The issue is cleared on the next view change.
This does not cause any functional issues in the cluster, but can cause repeated WARN
logs in some cases.
