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
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.
