Keep getting this stacktrace while testing notifications.

Sending alert, status=grace, code=11f7ef3e-bc25-4d85-8930-80090aab7418
Traceback (most recent call last):

    raise NotImplementedError("Unexpected status: %s" % self.status)

Notifications seem to work when ./manage.py sendalerts is invoked manually after 'check failure'. But when I start sendalerts in background I always get this stacktrace.

@bobelev can you please give a little more detail on the steps to reproduce this? If you have a test database, can you make a SQL dump and send it to me?

There was a race condition in sendalerts command (between selecting check and sending a notification, the status can go from "up" to "grace"), and I just fixed that. But I'm not sure it's the same issue you are seeing.
