Thanks Jonathan for this, can I ask the unmentionalble (which Linux implementation did you pick?). I had major problems installing with more than 4Gb but once I moved to stable we seemed to have a stable platform when doing basic stuff - we have two databases (mySQL) one is reasonably heavily used and one very extensively used. They sit on different servers to maximise performance. One worked perfectly for a couple of weeks while the other more extensive one repeatedly fell over. I think I agree wholeheartedly with your comments being a great supporter of FreeBSD it is a shame that the AMD release is not as super as the other versions we have used extensively. Thanks for your support. Regards ALan > -----Original Message----- > From: Jonathan A.
