[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1878) Duplicated Messages received during failover process
[
https://issues.jboss.org/browse/JBMESSAGING-1878?page=com.atlassian.jira....

Yong Hao Gao commented on JBMESSAGING-1878:
-------------------------------------------
There are two possible error cases:
1. a message arrives at client side and added to the buffer right after the list has been
cleared by failover (JBPAPP-6700).
2. a message just be removed from the buffer list but haven't been put into the ack
list before failover.
In either case the client will see the message twice.
Duplicated Messages received during failover process
----------------------------------------------------
Key: JBMESSAGING-1878
URL: https://issues.jboss.org/browse/JBMESSAGING-1878
Project: JBoss Messaging
Issue Type: Bug
Components: Messaging Core
Affects Versions: 1.4.0.SP3.CP12, 1.4.8.GA
Reporter: Yong Hao Gao
Assignee: Yong Hao Gao
Priority: Critical
Fix For: 1.4.0.SP3.CP13, 1.4.8.SP1
If a message is delivered to the client when failover happens, there is a chance that
this message won't get cleaned up and put into client buffer, and the message will be
recovered after failover and delivered to client so that the client may have received this
message twice.
