java.net.ConnectException thrown

[J. Mi]

All,

I get following exception pretty consistently when trying to concurrently
connect about 800 connections.

Any idea? Is this something out of Netty's control? If so, is there some
configuration I could do to JVM or operating system to increase resource
capacity?

Thanks,
Jason
