We are seeing ActiveMQIllegalStateException[errorType=ILLEGAL_STATE message=AMQ229027: Could not find reference on consumer ID=0 after stop & start of server

Test scenario: Producer sends messages to a topic. Diverts distribute them to 3 queues. When server starts paging, consumers and subscriber start receiving messages. During receiving server is restarted. Receivers can't fail during restart to pass the test.

Test sources: https://gitlab.mw.lab.eng.bos.redhat.com/jbossqe-eap/messaging-testsuite/blob/master/jboss-hornetq-testsuite/common-tests/src/test/java/org/jboss/qa/hornetq/test/diverts/DivertTestCase.java
Test failure: https://eap-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/eap-7.x-messaging-weekly-common-functional-matrix-rhel/238/jdk=openjdk-1.8,label_exp=RHEL6&&x86_64&&dynamic&&large/consoleFull

• Look for "RETRY receive for host" string.

To get a trace logs from https://eap-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/eap-7.x-messaging-weekly-common-functional-matrix-rhel/238/jdk=openjdk-1.8,label_exp=RHEL6&&x86_64&&dynamic&&large/console just follow:

wget 'https://eap-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/eap-7.x-messaging-weekly-common-functional-matrix-rhel/jdk=openjdk-1.8,label_exp=RHEL6&&x86_64&&dynamic&&large/239/artifact/logs.zip'
# server logs could be found there as well
unzip logs.zip eap-testsuite/jboss-hornetq-testsuite/common-tests/target/test-suite.log
vim eap-testsuite/jboss-hornetq-testsuite/common-tests/target/test-suite.log
# serach for "RETRY receive for host"

Unfortunately I'm neither the test author, not the JMS enthusiast, but I can try to provide more details if required.

We're seeing the test failure in ~5% of test runs, no metter the platform or JDK.

Not an regression as looking to the test case git history, I'd tell the test was intermittently failing ever since it was introduced.
