-------------------------------------
Summary: "Soft deadlock" in TransportConnection causes degraded
performance in certain situations
Key: AMQ-5109
URL: https://issues.apache.org/jira/browse/AMQ-5109
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.9.0
Environment: HP-UX 11.31, RHEL 5/6. HP JDK 6/7, Oracle JDK 6/7
Reporter: Nikolay Martynov
Priority: Minor
"Soft" deadlock occurres due to async stopping in case of starting/stopping
lots of client connections (using jms template with standard connection
factory, for example). ActiveMQ BrokerService gets frozen for 1 second trying
to acquire the lock. As a result, already poor performance in case of unpooled
connection factory further degrades by around 50%.
