------------------------------------
Summary: Deadlock in InactivityMonitor when using Failover
Key: AMQNET-488
URL: https://issues.apache.org/jira/browse/AMQNET-488
Project: ActiveMQ .Net
Issue Type: Bug
Components: ActiveMQ
Affects Versions: 1.6.2
Environment: ActiveMQ 5.10.0 on Windows Server 2012
Apache.NMS.ActiveMQ 6.2 on .Net 4.5 + Windows 7
Reporter: Laurence Pike
Assignee: Jim Gomes
Priority: Critical
Can occur when FailoverTransport is disposing the transport when the inactivity
monitor fires. Deadlock between InactivityMonitor.monitor and
CompositeTaskRunner.mutex.
Stack traces for deadlock:
