--------------------------------------------
I have applied the suggested patch fully. Can you give it a try using the
packages I have created and posted on [people.apache.org/~elecharny] ?
> SSLHandler writes corrupt messages under heavy load
> ---------------------------------------------------
>
> Key: DIRMINA-1027
> URL: https://issues.apache.org/jira/browse/DIRMINA-1027
> Project: MINA
> Issue Type: Bug
> Components: SSL
> Affects Versions: 2.0.11
> Reporter: Michael Kohlsche
> Priority: Critical
>
> I’m facing a critical problem in my project with an MINA-stack including SSL.
> My Protocol-IoFilterAdapter receives corrupt messages under heavy load
> (JMeter-Benchmark with 300 Threads and round about 5-10 MINA-calls per
> thread). The Problem disappeared without SSL, so I debugged for some days,
> and I think the problem occurred because of the changes made for fixing the
> issue [DIRMINA-1019|https://issues.apache.org/jira/browse/DIRMINA-1019]
> ([commit|http://git-wip-us.apache.org/repos/asf/mina/commit/9b5c07f9]). I
> think the problem is that the SSLHandler is calling messageReceived while
> also writing data into the next filter, which is writing inside the
> messageReceivedEventQueue. With the fix provided inside the
> race-condition-ticket, it works like a charm. So I think that the answer of
> the question "Why the second loop is also protected by the loop?" is: because
> otherwise the messageReceivedEventQueue gets corrupted data...
> (I hope I’m not wrong and anybody can follow my thoughts and maybe bad
> English)
