-------------------------------------
> Unexpected OutOfMemoryError exception in SocketConnectorIoProcessor
> -------------------------------------------------------------------
>
> Key: DIRMINA-320
> URL: https://issues.apache.org/jira/browse/DIRMINA-320
> Project: MINA
> Issue Type: Bug
> Components: Transport
> Affects Versions: 1.0.0
> Environment: Mac OS X, Java 1.5.0_06
> Reporter: Matthew Phillips
> Assignee: Trustin Lee
>
> I'm not totally sure that this is a bug, but it's certainly a problem in that
> the error is partially hidden by being sent to the logger and not the
> exceptionCaught() method and seems to leave MINA in an unusable state.
> The scenario is that I'm running some memory load tests by having a client
> fire lots of large messages at a server, and I occasionally see the sort of
> exception below appear on the client's console (the client is also
> MINA-based). It appears the heap is being blown and not being handled very
> gracefully. The client that sees this happen does not shut down cleanly,
> possibly because it's no longer able to send/receive the messages needed by
> my protocol to close the session.
> The main problem is that the client has no idea this has happened and cannot
> take any action, it just fails ungracefully.
