Boy thats a bummer. I have some of the Sun Fire X4100 M2 servers and Oracle support told me that they are not supported hardware for 3.2.1. I just figured that it was not certified for the X4100s. I have 3.2.1 running on HP DL385 G7s, but would have thought that Oracle would have concentrated on making it work on all its own hardware. Since it did not work for you, my hopes for running it on my older servers have now dropped.
