just a quick question once i have more then a few miners pointing toward mmpool i get massive rejects it seems to be based on amount of hash per my user account once i get over 15th/s i have major issues

just had to send 40 th/s elsewhere cause getting 70% rejects or more
Are you adjusting your difficulty accordingly? With 40TH/s, you should be using around 56,000 difficulty.
Yes, this is the usual reason for hight rejects. Set your password to "d=x" where 'x' is 56000 for 40TH/s. Automatic difficulty adjustment is in progress.
