[jboss-jira] [JBoss JIRA] (JGRP-1382) VERIFY_SUSPECT can kick a live node soon after it re-joins

[Dennis Reed (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638635#comment-12638635 ] 

Dennis Reed commented on JGRP-1382:
-----------------------------------

Fix is for VERIFY_SUSPECT to listen for view changes, and remove timers for any members that are no longer in the view.

In the scenario in the description, it would be removed when the node is originally kicked,
and would not be kicked again.

> Due to a timing issue, VERIFY_SUSPECT can kick a good member from the cluster soon after joining.
> A live node currently in the cluster stops responding temporarily (garbage collection, NIC down, etc).
> FD sends up a suspect message to VERIFY_SUSPECT.
> VERIFY_SUSPECT times out and sends up the suspect message.
> Before the node is kicked from the cluster, FD sends up another suspect message to VERIFY_SUSPECT.
> Node is kicked from the cluster.
> Node resumes, is shunned, and rejoins.
> VERIFY_SUSPECT times out and sends up the suspect message.
> Node is kicked from the cluster again.
