[jira] Commented: (AMQ-662) Infinite Loop after message resend
[ https://issues.apache.org/activemq/browse/AMQ-662?page=comments#action_35941 ]
John Pederzolli commented on AMQ-662:
-------------------------------------
I've been looking into this further and it appears to be a synchronization issue in or related to ServerSessionImpl.java. If I individually send messages which are then forced to resend, everything works fine. This infinite loop only occurs when I send several messages in a row.

> when a runtime exception in onMessage the messages are getting rolledback/resent as expected, however AMQ appears to go into an infinite loop at this point taking up 100% of the CPU. Turning debug on shows the following repeated:
> ...
> [DEBUG] 2006-03-21 16:55:37,586 - org.apache.activemq.ra.ServerSessionImpl:1 (ServerSessionImpl.java:159)- run loop start
> [DEBUG] 2006-03-21 16:55:37,586 - org.apache.activemq.ra.ServerSessionImpl:3 (ServerSessionImpl.java:172)- run loop end
> [DEBUG] 2006-03-21 16:55:37,586 - org.apache.activemq.ra.ServerSessionImpl:22 (ServerSessionImpl.java:172)- run loop end
> [DEBUG] 2006-03-21 16:55:37,586 - org.apache.activemq.ra.ServerSessionImpl:11 (ServerSessionImpl.java:159)- run loop start
> [DEBUG] 2006-03-21 16:55:37,586 - org.apache.activemq.ra.ServerSessionImpl:0 (ServerSessionImpl.java:172)- run loop end
> [DEBUG] 2006-03-21 16:55:37,586 - org.apache.activemq.ra.ServerSessionImpl:17 (ServerSessionImpl.java:172)- run loop end
> [DEBUG] 2006-03-21 16:55:37,586 - org.apache.activemq.ra.ServerSessionImpl:1 (ServerSessionImpl.java:172)- run loop end
> The resend (and resulting infinte loop) was triggered by throwing a RuntimeException in the onMessage method of the POJO MDB.
> This is being used alongside Spring 1.2.7, Jencks 1.1.1 in a POJO message driven bean setup. Attached are the configurations producing the error.
