ASF GitHub Bot commented on STORM-1190: --------------------------------------- Github user revans2 commented on the pull request: https://github.com/apache/storm/pull/870#issuecomment-155499487 I'll give it a try and see how it works. I'll probably change the TIMER to be an actual Timer though. > 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 > Attachments: Screenshot 2015-11-08 22.17.57.png, Screenshot > 2015-11-08 22.18.06.png > > > 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.
