> We've been running Storm's snapshots on our production cluster for a little
> while now (that back pressure support really helped us), and we've noticed a
> sudden spike in system load when going from
> commit@ba1250993d10ffc523c9f5464371fbeb406d216f to the current latest
> commit@c12e28c829fcfabc0a3a775fb9714968b7e3e349. Both versions were running
> the exact same topologies, and there was no significant change in workload.
> Not exactly sure how to even begin to debug this, so we ended up just rolling
> back. Thoughts?
> Stats screenshots attached
