If you haven't already taken their advice and gone to 4.4.0f then do so.We have been informed that the code was forked at 4.4.0b and will not reach parity with 4.4.0f until 5.0.1d (go figure!).
Thanks Alastair, I just added 2 new 4100 with 5.0.1b on to our SAN . Nothing is connected yet, so I will revert that code to 4.4.0f.
