Queue not processing, error

I just switched to queue email sending, but even though my cron is set properly, it will not process. Here is what my log says:

[2016-08-10 22:30:03] mautic.NOTICE: SymfonyComponentConsoleExceptionRuntimeException: Too many arguments. (uncaught exception) at /home/PATH/go/vendor/symfony/console/Input/ArgvInput.php line 179 while running console command mautic:emails:send [] []



Prior to this I tried to email 5,500 contacts, 1400 sent, then no matter what I did it would no longer send.



Any thoughts?



Thanks in advance.

I tested throttling all the way down to just sending 20 and having the cron run ever 10 minutes. Same error in the logs unfortunately.
