Claus Ibsen created AMQ-3997:
--------------------------------
Summary: Memory leak in activemq-pool
Key: AMQ-3997
URL: https://issues.apache.org/jira/browse/AMQ-3997
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.6.0
Reporter: Claus Ibsen
Fix For: 5.7.0
The org.apache.activemq.pool.PooledConnectionFactory from activemq-pool has a
severe memory leak when using it for sending a lot of messages. Over time this
causes memory to be eaten up.
I have tracked it down to the following tickets:
- AMQ-3680, which keeps adding event listeners, despite previously added
- AMQ-2643, code which keep track of loaned sessions, causing JVM to create too
many ConcurrentLinkedQueue$Node instances
There may be others. But with resolutions to those I can get the pool to not
eat memory, and keep memory consumption low.
