possible livelock detected in app server under heavy load
During a few load load-test sessions the server would reach high CPU usage and enter some sort of livelock which will keep it spinning (at least one CPU core would be at 100%). All connections to the server would hang and no more action would be possible except killing it.
This has been reproduced a couple of times by applying a significant load to the server (~3000 simulcontrollers on a single app instance server).
I've attached the log of a stack trace from an affected server.
QA Test Steps
No QA required for this one as this has been hard to repro. And there is no code change in Mattermost.
Thanks, closing, no further testing required.
