ASF subversion and git services commented on QPIDJMS-438:
---------------------------------------------------------

Commit 26ec26863410ddf11097054987764b93567a4663 in qpid-jms's branch refs/heads/master from
[~tabish121]
[ https://git-wip-us.apache.org/repos/asf?p=qpid-jms.git;h=26ec268 ]

QPIDJMS-438 Ensure that closed sessions are removed from tracking

When a session is remotely closed it can be left in the Connection
tracking map which can lead to large leaks of remotely closed sessions
over time.  Ensure it is removed on shutdown calls.

> We use Qpid JMS to connect to the Azure service bus.
> In our applications we cache the connections in a pool and cache a session for each connection
for sending messages.
> When Azure believes the connection is idle for 5 minutes it is remotely closed. Resulting
in closing the cached session in the application. The application responds by replacing the
cached session with a newly created session.
> The problem here is that the closed sessions are not removed from the connection. Eventually
resulting in an OutOfMemoryError.
