[jira] [Created] (AMQ-5109) "Soft deadlock" in TransportConnection
causes degraded performance in certain situations
Nikolay Martynov created AMQ-5109:
-------------------------------------
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%.
