Subject Re: SocketSessionImpl in Mina component retained in memory indefinitely
Date Wed, 17 Feb 2010 14:49:38 GMT
Hi

Could you google that exception and see what other Mina users have encountered.

And you see this DEBUG logging when you send to that remote endpoint?

            if (LOG.isDebugEnabled()) {
                LOG.debug("Closing session when complete at address: "
+ endpoint.getAddress());
            }
