Michael, My original post was titled "Client Connection Timeouts" and it was posted in early June, you can take a look at that for details.
In summary we found the issue with 2.0 M5 and M6 and attempted a variety of configurations to resolve the issue to no avail. We are still using the Mina SSHD package, but have ported it to run on top of Netty which seems to behave much better under heavy load. We also found that NIO does not really perform well in general when compared to blocking I/O using NPTL. Unless your app must maintain an extremely large number of long lived connections I would recommend going with blocking I/O if you are performance sensitive.
