I know that the S5000XVN is a recent board and all, and maybe they can provide you with some helpful tips in determining the root cause of your issue. I would suggest doing what Jeff suggested, with enabling KDB, WITNESS, INVARIANTS, and the like. I would consider also disabling SMP for a while and see if the issues persist. What scheduler are you using? Also, is there a common point where your server's running into issues under load, with particular programs? -Garrett
