seeing the same thing on one of my older M/S apps. Nothing has changed in code but most of the request have huge latency with most in the pending_ms queue. I started messing with the sliders to see if anything worked but prior to that (when its been busted for several days), the sliders were both on full automatic. 4-7 instances running at any one time and minimal traffic
