--------------------------------------
Fix Version/s: 2.0.8
> Possible Deadlock/Out of memory when sending large amounts of data using Nio

>
> Key: DIRMINA-789
> URL: https://issues.apache.org/jira/browse/DIRMINA-789
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-RC1
> Environment: Windows Vista 64-bit Java 5 and Java 6
> Reporter: Sai Pullabhotla
> Fix For: 2.0.8

>
> This is a followup to the post on the DEV mailing list,
> http://old.nabble.com/Help-needed-with-OutOfMemory-error-and-or-GC-Issues-Dead-Locks-td28849756.html.
>
> I've even simplified the test cases so now it just has one simple NioServer,
> and an NioClient. The MinaClient class creates 5 concurrent connections to
> the RandomDataServer. Upon a successful connection, the server is setup to
> send 500MB worth of random text data. The MinaClient just saves the received
> data to a temp file in the working directory. When I run this code with small
> amounts of data, it works fine, but with 500MB, I did not have success yet.
> Some times, I get OOM on the server. Some times, nothing happens.
> I've declared several constants in each class that you could change to try
> various settings such as changing the amount of data served by the server,
> whether or not to use an executor filter/IoEventThrottle etc.
> Both classes have main methods, and I was running them as stand alone
> applications on the same PC.
