[jira] [Created] (STORM-1190) System load spikes in recent snapshot

Michael Schonfeld created STORM-1190:
----------------------------------------

             Summary: System load spikes in recent snapshot
                 Key: STORM-1190
                 URL: https://issues.apache.org/jira/browse/STORM-1190
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-core
    Affects Versions: 0.11.0
         Environment: 10x (CoreOS stable (766.4.0) / k8s 1.0.1 / docker running on Azure VMs)
            Reporter: Michael Schonfeld
            Priority: Critical


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?
