Right about the time i noticed the scheduler had started cycling instances 
every 3-4 minutes, I also noticed that our QPS has dropped to 30% of what 
it used to be.
Instead of ~1 QPS average we now have 0.3 QPS average.
Seems to be the same for Master/Slave and HR datastore apps.

Anybody else noticed similar?
