Active MQ version 5.X - java 5 - memory leaks
----------------------------------------------
Key: AMQ-1626
URL: https://issues.apache.org/activemq/browse/AMQ-1626
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.0.0, 5.1.0
Reporter: Michal Singer
Priority: Blocker
Attachments: ClientExecuterController.java, JmsListener.java,
JmsResponseSender.java
when working with jdk1.5 and activemq 5.X. there are problems with memory leaks.
I use an embedded broker configured in spring 2.0.8.
I have a client application (producer ) and a server (consumer) which inside
it the broker.
The client uses PooledConnectionFactory, creates one connection, 2 sessions
(receive and send), and 1 producer.
the client connects to 2 queues defined in the broker (configured in spring),
and sets the "reply to" to a temporary queue.
The server receives the messages from the client, does some processing, and
returns a reply on the temp q.
each request is handled by a diiferent temp q. the temp q is deleted once the
client receives the responses.
All resources are deleted on client side. the server is hanlded by spring. the
server responses on the temp queues.
During run, i see a few problems (in jconsole)
1. memory of broker increases gradually and never released
2. memory of temp queues increases gradually and never released
3. advisory topic node is created with many objects under it - which seem like
with the same ids as some of the temp queue. they accumulate,
and are never released.
These leaks prevent me from working,. the activemq will stop working after a
few hours due to 100%memory consumption.
There are also memory leaks concerning temp queues usage.
I tried creating one connection on client or using a pool of connections but
nothing helped.
It looks like some memory leak on the temp queues.
Do you have a work around for these problems, when will there be fixes for
these problems?
If i will use a static queues, will all the leaks in the broker be solved?
If i create a new connection for each request process, should this solve the
problem? (checked - does not work)
I attached the client (producer) code and the server (consumer)
