don't think so, but my stuff was pretty heavily customized anyways. The bug itself is in payout.php, fwiw. thesilverwolf pool op has some posts somewhere with more details, as I believe his SBC pool was hit with it early on.
Yea i am googling it.
Either people are trying to do many manual payouts in less then a second or there is a race condition between manual and auto
payouts via the scripts. I am using greedi's fork.
