I'm trying to run a campaign in live mode, and it seems to not be able to start any HITs (after 8 minutes, no HITs have been created per the Dashboard)
Starting a campaign with a 2 minute interval between HITs, server.log for relevant time period:

It seems like maybe the wakeup and runtime code is in some sort of race condition, where we don't wake up until slightly after the desired runtime, and then fall back to trying again 2m later, etc?
