-------------------------------------
Summary: NullReferenceException from
Apache.NMS.ActiveMQ.Transport.InactivityMonitor
Key: AMQNET-401
URL: https://issues.apache.org/jira/browse/AMQNET-401
Project: ActiveMQ .Net
Issue Type: Bug
Components: NMS
Affects Versions: 1.5.6
Environment: Windows Server 2008 R2, .Net 4.0
Reporter: Markus Karolus
Assignee: Jim Gomes
Priority: Critical
It's the same problem which is descibed in,
https://issues.apache.org/jira/browse/AMQNET-339
in the current version (1.5.6) the real problem is not fixed, so I created this
new issue.
Today we had an crash on one of our enviromental boxes:
Directly after a failover we got the following message from the
InactivityMonitor "InactivityMonitor[{0}]: Timer Task didn't shutdown properly."
Afterwards the whole process shuts down after an UnhandledException handling.
In the WriteCheck method a NullReferenceException was thrown.
It seems that during the StopMonitorThreads the timer connectionCheckTimer
couldn't stop correctly and ansyncTasks exists. Directly after that the
asyncTasks will be set to null -> In the currenr running WriteCheck a
NullReferenceException occures.
(This problem was already commented in AMQNET-339 as last comment from Matthew
Good)
