Yesterday we introduced a bunch of performance enhancements to the
system. During the course of letting the system run overnight, we have
detected a bug that keeps results from being sent to hosts. It looks
at though this bug has only been around for about 13 hours. While we
are debugging this issue we have decided to shutdown the scheduler
and try and let the transitioners pick up the pace a bit.
