Gary Tully commented on AMQ-3495:
---------------------------------
so that stack trace indicates that it is waiting for a commit reply from the
broker, do you have a corresponding thread dump from the broker to see why that
request is blocked?
> Active MQ 5.4.2 - Message stuck due to connection hung for amq client
> ---------------------------------------------------------------------

> Key: AMQ-3495
> URL: https://issues.apache.org/jira/browse/AMQ-3495
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.4.2
> Environment: RedHat Linux 2.6.18-194.11.1.el5
> AMQ 5.4.2
> WebSphere Application Server 7.0
> Reporter: Rahul Shinge
> Priority: Blocker

> Hi - Here is high level overview of response flow using Active MQ
> Destination System JMS Client -> AMQ Response Queue -> Firewall -> Source
> System JMS Client
> Firewall timeout = 30 min
> Current volume = approx 6400 messages/day -- 400 messages/10 min
> Source system JMS (WebSphere) client is connected to AMQ Broker using JMS API
> and AMQ 5.4.2 libraries. We are experiencing intermittent issue in PRODUCTION
> -- Source system client connection gets hung and requires restart to process
> pending message on queue. At this point we are not able to reproduce this
> issue at will but it occurs in PRODUCTION intermittently.
> Here is tracing from Websphere client which shows
> org.apache.activemq.ActiveMQSession.commit was called but didn't succeed.
