Messages get stuck in the queue for some client sessions, "Dispatched Queue"
grows but "Dequeues" doesn't move
--------------------------------------------------------------------------------------------------------------
Key: AMQ-3460
URL: https://issues.apache.org/jira/browse/AMQ-3460
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.3.1
Environment: java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_15-b04, mixed mode)
Reporter: Timur Evdokimov
Priority: Critical
We experience the following problem.
There's 1 sender thread and 20 listener threads operating on the same queue.
No other queues are involved.
Message traffic goes generally OK via the queue, however Number of pending
messages goes up one by one.
Looking at the active customers list, the following appears (see attached
screenshot).
For all sessions but two, the messages are dispatched properly.
For these two affected sessions, the "Dispatched Queue" value gots stuck at
certain moment and doesn't deliver anymore.
Eventually, more sessions got affected, and maybe after some hours, the stuck
messages got delivered.
What we tried - adding useCache="false" into <policyEntry queue=">" ... > tag.
Didn't have any effect.
