Dispatcher threads do not die
-----------------------------
Key: QPID-607
URL: https://issues.apache.org/jira/browse/QPID-607
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: M2
Environment: Any
Reporter: Robert Greig
Assignee: Robert Greig
During extensive testing we see many (e.g. hundreds) of threads running with
the following stack:
"Dispatcher-Channel-1" daemon prio=1 tid=0x00002aab004e6530 nid=0x5d24
waiting on condition [0x0000000052978000..0x0000000052978c00]
at sun.misc.Unsafe.park(Native Method)
at java.util.concurrent.locks.LockSupport.park(LockSupport.java:118)
at
java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:1767)
at
java.util.concurrent.LinkedBlockingQueue.take(LinkedBlockingQueue.java:359)
at
org.apache.qpid.client.util.FlowControllingBlockingQueue.take(FlowControllingBlockingQueue.java:74)
at org.apache.qpid.client.AMQSession$Dispatcher.run(AMQSession.java:2680)
This is because the dispatcher does a blocking take, rather than a poll with a
timeout.
