Deadlock with acknowledgement
-----------------------------
Key: AMQNET-132
URL: https://issues.apache.org/activemq/browse/AMQNET-132
Project: ActiveMQ .Net
Issue Type: Bug
Components: ActiveMQ Client
Environment: Windows Quadcore machine, running Visual Studio 2008, and
.NET 2.0
Reporter: Christian Gross
Assignee: Jim Gomes
When I send and receive very large number of text based messages the code doing
the receiving will lock up. This behavior occurs when you use async or the
IMessageConsumer.Read method.
The problem is that when the Receive method is called it calls the CheckClosed.
In the method CheckClosed there is a lock(this) statement, and it is waiting
for the lock to be released. The problem is that the method Dispatch that also
uses the same lock is deadlocked on something. In specific the following line
is the deadlock:
ackSession.Connection.OneWay(ack);
If I switch the session settings from AutoAcknowledge to ClientAcknowledge then
I can retrieve all of the messages without any deadlocks occurring.
