ASF subversion and git services commented on ARTEMIS-4312: ---------------------------------------------------------- Commit 3ff8419a4b0e32bff5b43997d09db9a9acc28586 in activemq-artemis's branch refs/heads/main from Justin Bertram [ https://gitbox.apache.org/repos/asf?p=activemq-artemis.git;h=3ff8419a4b ] ARTEMIS-4312 dupes w/redistribution and multicast Multiple multicast queues on the same address can lead to duplicate messages during redistribution in a cluster. > Duplicates with redistribution and multiple multicast queues on the same > address > -------------------------------------------------------------------------------- > > Key: ARTEMIS-4312 > URL: https://issues.apache.org/jira/browse/ARTEMIS-4312 > Project: ActiveMQ Artemis > Issue Type: Bug > Affects Versions: 2.28.0 > Reporter: Justin Bertram > Assignee: Justin Bertram > Priority: Major > Time Spent: 40m > Remaining Estimate: 0h > > Consider a set-up with two brokers clustered together and redistribution > enabled and a address with about a dozen multicast subscription queues bound > to it. If a consumer of one of those subscriptions goes offline, messages > will begin to build up in the queue (as expected). When the consumer comes > back online, whatever broker it attaches to first will have messages > redistributed from the other broker in the cluster. When this redistribution > happens the other multicast queues receive some of those redistributed > messages (although not all of them) even though they had already received > them previously. -- This message was sent by Atlassian Jira (v8.20.10#820010)
