RE: 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?
