Summary: Critical IO Error ... when starting Artemis with HA JDBC store
Key: WFWIP-93
URL: https://issues.jboss.org/browse/WFWIP-93
Project: WildFly WIP
Issue Type: Bug
Components: Artemis, JMS
Reporter: Peter Mačkay
Assignee: Martyn Taylor
Priority: Blocker
One of the servers in collocated HA topology with JDBC store can fail on critical IO
exception and stop itself.
This was hit on Artemis 1.5.5.012 and WF: https://github.com/jmesnil/wildfly -
WFLY-9513_messaging_jdbc_HA_shared-store branch.
Test scenario:
* Start 2 WF/EAP servers in collocated topology with Artemis HA JDBC store
* Start client which are sending and consuming messages to/from queue from 1st server
Result:
There is intermittent failure when client start to send/receive messages on 1st server.
1st fails on Critical IO Error with exception:
