[ https://issues.jboss.org/browse/WFLY-10067?page=com.atlassian.jira.plugin... ] Erich Duda updated WFLY-10067: ------------------------------ Description: Failover does not work with HTTP connectors/acceptors. *Scenario:* # There are two Wildfly servers configured as Live-Backup pair # There is one JMS producer and one JMS receiver which sends/receives messages # Live server is several times killed and restarted. *Expectation:* Always when the Live server is killed or restarted, clients do failover or failback. *Reality*: Sometimes happens that clients don't do failover. *Users impact:* One of basics feature of HA, failover, does not work properly. *Blocker* priority was set because this is regression against previous releases of Wildfly. *Detail description of issue* In the trace logs it can be seen that clients send HTTP handshake request to active backup, but the handshake fails. All checks (and logs) say that the backup is active in this time period. I tried to run the test with Netty connectors/acceptors and I didn't see this issue. {code:title=Backup log} 07:52:47,856 WARN [org.apache.activemq.artemis.core.server] (Thread-2 (ActiveMQ-IO-server-org.apache.activemq.artemis.core.server.impl.ActiveMQServerImpl$6@1f01f347)) AMQ222029: Could not locate page transaction 3 995, ignoring message on position PagePositionImpl [pageNr=2, messageNr=55, recordID=-1] on address=jms.queue.testQueue queue=jms.queue.testQueue 07:52:47,856 WARN [org.apache.activemq.artemis.core.server] (Thread-2 (ActiveMQ-IO-server-org.apache.activemq.artemis.core.server.impl.ActiveMQServerImpl$6@1f01f347)) AMQ222029: Could not locate page transaction 3 995, ignoring message on position PagePositionImpl [pageNr=2, messageNr=56, recordID=-1] on address=jms.queue.testQueue queue=jms.queue.testQueue 07:52:47,863 INFO [org.apache.activemq.artemis.core.server] (AMQ119000: Activation for server ActiveMQServerImpl::serverUUID=null) AMQ221005: Deleting pending large message as it was not completed: Pair[a=2147485068, b=2147485067] 07:52:47,863 INFO [org.apache.activemq.artemis.core.server] (AMQ119000: Activation for server ActiveMQServerImpl::serverUUID=null) AMQ221005: Deleting pending large message as it was not completed: Pair[a=2147485076, b=2147485075] 07:52:47,864 INFO [org.apache.activemq.artemis.core.server] (AMQ119000: Activation for server ActiveMQServerImpl::serverUUID=null) AMQ221005: Deleting pending large message as it was not completed: Pair[a=2147484450, b=2147484449] 07:52:47,864 INFO [org.apache.activemq.artemis.core.server] (AMQ119000: Activation for server ActiveMQServerImpl::serverUUID=null) AMQ221005: Deleting pending large message as it was not completed: Pair[a=2147485072, b=2147485071] 07:52:47,864 INFO [org.apache.activemq.artemis.core.server] (AMQ119000: Activation for server ActiveMQServerImpl::serverUUID=null) AMQ221005: Deleting pending large message as it was not completed: Pair[a=2147484454, b=2147484453] 07:52:47,866 WARN [org.apache.activemq.artemis.core.client] (activemq-discovery-group-thread-dg-group1) AMQ212034: There are more than one servers on the network broadcasting the same node id.
