Slave threads increasing when sending to temporary queue
--------------------------------------------------------
Key: AMQ-1849
URL: https://issues.apache.org/activemq/browse/AMQ-1849
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.2.0
Environment: Pure master/slave
JBoss 4.0.5 GA (on Java 1.5.0_14)
few days old ActiveMQ 5.2.0-SNAPSHOT (on Java "1.6.0_06")
Reporter: Hans Bausewein
Attachments: activemqjee-0.0.1-src.tar.gz, jboss.log
Deployed the attached TextMDB (modified JBoss example) to our JBoss 4.0.5 GA
server (cluster).
- send a message to "queue.A" with Reply To set to "queue.REPLY_A"
The TextMDB bean:
- creates a temporary queue with NON_PERSISTENT delivery mode
- forwards message body to "queue.B" and sets the reply queue to this
temporary queue
- another (or the same) instance of TextMDB replies and adds some text,
replies to the temporary queue
- the first TextMDB replies to "queue.REPLY_A"
Works fine, except that every time a temporary queue message is sent, the
number of threads on the slave increases by 3.
On the master the threads are destroyed after a while, but on the slave they
persist, growing to "OutOfMemoryError: unable to create new native thread"
Temporary queue Thread Name example: TempQueue:
ID:{HOSTNAME}-59619-1215591084487-0:16:5
+ 2 topic threads
That thread ID can be found ActiveMQ messages in the attached JBoss log.
Have I created a bug im my code or have I found a bug in the ActiveMQ server?
