[jboss-jira] [JBoss JIRA] (WFLY-10102) JCA RA inflow connections are not always well balanced

JCA RA inflow connections are not always well balanced ------------------------------------------------------ Key: WFLY-10102 URL: https://issues.jboss.org/browse/WFLY-10102 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 12.0.0.Final, 14.0.0.Final Reporter: Erich Duda Assignee: Jeff Mesnil Priority: Major Attachments: server1-trace.1.zip, server1-trace.2.zip, server1-trace.3.zip, server1-trace.zip, server1.zip, server2-logs.zip, server3-logs.zip, server4-logs.zip, test.log.zip *Scenario* * There are 4 Wildfly servers. Severs 1, 3 are in cluster. * Queue InQueue is deployed to servers 1,3. * Servers 2 and 4 have RA configured to connect to servers 1 and 3 server. * Start servers 1,3 and send 10000 (~1Kb) messages to InQueue * Start servers 2,4 with MDB consuming messages from InQueue and sending to OutQueue. * When MDBs are processing messages, restart (clean shutdown and start) servers in this order: 1,2,4,3 * Wait until all messages are processed. * Measure number of consumers on InQueue on servers 1 and 3. * Difference between number of consumers must be <= 2. *Expectation:* Number of consumers on servers 1 and 3 are almost equal. *Reality:* Number of consumers on servers 1 and 3 are sometimes different. E.g. server 1 has 19 consumers and server 3 has 11 consumers. Note: this is not regression. I can see this issue also with Artemis 1.5.x.
