Timothy Bish commented on ARTEMIS-1286:
---------------------------------------

[~pwjenkins] The folks working an the ActiveMQ project are in many cases 
working on issues on there own time or in coordination with other pressing 
matters in their day jobs.  Pressing people who are volunteering their time and 
energy to fix your problem is usually a good way of annoying people into 
ignoring you.  Artemis is an open source project, you can dive in and try and 
resolve issues as anyone else can, I'd recommend you take some time and try and 
see if you can fix your own issue.

> Originally seen in v2.1 and present in v2.2.
> If you send and receive a lot of 2MB messages in short time thru Artemis via 
> Netty connector, the server throws the following OutOfDirectMemoryError 
> exception. The server stops responding and will not (any longer) accept 
> connections without throwing exceptions in an infinite loop.
