      Description

      I am having some application using Mina 2.0.7 which is getting huge amount of SSL Handshake errors (7 million per day) because old clients do not accept the server certificate, and is leaking quite much memory.

      I have checked that we are not leaking because of leaving open connections. We are properly closing those ether by timeout or exception. But still leaking quite much.

      The only reason that I really think about is that when the client send the "bad certificate" message and the SSL Handshake fails, there would be some memory which is not properly released.

      These are the logs which corresponds to one failed request:
