RE: Virtual Memory

OK - are your clients using more memory than expected?
Its possible there is a leak in the server, but it could
also be that your clients are creating sessions, producers and consumers, 
and not closing them.

Subject: RE: [openjms-user] Virtual Memory



I have two applications that open a single connection to the OpenJMS server.
My applications do not send a lot of information via messaging, they are
only used as a bridge to each other so my Connection is in a singleton which
will maintain one open connection while the application is running. It is
closed only when the server is shut down. I will change this to a connection
pool in the near future which will open and close the connections while the
bridge is not being used, but have not coded that part yet.

Are any clients active?  Is it possible they may be
failing to close connections/sessions etc?
