    Hmmm... have you talked to Intel yet? 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?
