Emmanuel Lecharny updated DIRMINA-968:
--------------------------------------
Fix Version/s: 2.0.8
> Memory leak in SSL Handshake errors
> -----------------------------------
>
> Key: DIRMINA-968
> URL: https://issues.apache.org/jira/browse/DIRMINA-968
> Project: MINA
> Issue Type: Bug
> Components: Handler
> Affects Versions: 2.0.7
> Environment: Centos
> Reporter: Enrique Cordero
> Priority: Critical
> Labels: memory-leak
> Fix For: 2.0.8
>
> Original Estimate: 96h
> Remaining Estimate: 96h
>
> 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:
