Gary Tully created AMQ-4791:
-------------------------------
Summary: [org.apache.activemq.ActiveMQConnection] dispatch paused,
waiting for outstanding dispatch interruption processing (1) to complete..
Key: AMQ-4791
URL: https://issues.apache.org/jira/browse/AMQ-4791
Project: ActiveMQ
Issue Type: Bug
Components: Transport
Affects Versions: 5.8.0
Reporter: Gary Tully
Assignee: Gary Tully
Fix For: 5.9.0
Race condition between consumer close and transport calculation of outstanding
interruption processing. Transport thinks there are more responses required
before allowing dispatch due to a mis count of active consumers.
NOTE: This is issue was initially reported using the Spring DMLC with the AMQ
rar deployed in a J2EE container. However it can be replicated the issue with a
simple JMS client creating a new consumer and closing the consumer for every
call to consumer.receive(1000).
The client AMQ connection appears to stop dispatching messages to the consumer
and continuously logs the following message
WARN [org.apache.activemq.ActiveMQConnection] (ActiveMQ Transport:
tcp://localhost/127.0.0.1:61616@51487) dispatch paused, waiting for outstanding
dispatch interruption processing (1) to complete..
