Hi rajdavies,

Hi moreno,
can you take a stack trace of the broker ? - the threads should be
getting garbage collected
thanks,

I confirm Marcin's problem (with AMQ 5.3).
One producer (java application with transport=openwire)
For each message producer open a Connection, send a msg, close the
Connection.
Server side no problem for what concern file descriptors opened,
memory usage, socket opened (with netstat I see all
conn=ESTABLISHED).
Problems with threads.
A new thread is created (inside AMQ) for every producer's open-send-
close.
Threads don't disappear even if producer call connection.close()
(they disappear after 20-30 seconds from producer's death).
In activemq.xml I set producerFlowControl=false,
transport.closeAsync=false.
AMQ run with these options:
-Xmx1024M, -Dorg.apache.activemq.UseDedicatedTaskRunner=false.
Producer set jms.useAsyncSend=false.
Are there other configurations I can try to stop thread's increment?
Many thanks

Hi,
I'm using ActiveMQ 5.2 and I've noticed thad ActiveMQ create new
thread
for every connection but even the client will disconnect its thread
still
alive (state RUNNABLE). It is ActiveMQ normal behavior?
Can I change this? I would like to finalize thread if client will
dissconnect.
Cheers,
Marcin
