Description

« Hide

1. Grab the test case in PROD-468.
2. Modify the connection factory in the Spring beans file to point to a local broker (say localhost:61616).
3. Load up MB 5.4.1-fuse-01-00 with the attached activemq.xml
4. Run the PROD-468 test case with

mvn clean compile exec:java -Dexec.mainClass=Main

5. Watch as the SimpleAuthenticationBroker accumulates memory. In the test case it does this very slowly, but in production scenarios it can grow much faster (800+MB in PROD-468). jmap shows 8448 instances after a few dozen minutes:

janstey@mojo:~$ jmap -histo <amq-pid> | grep SimpleAuthenticationBroker
  80:           264           8448  org.apache.activemq.security.SimpleAuthenticationBroker$2
 608:             1             40  org.apache.activemq.security.SimpleAuthenticationBroker
