> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.10.0
> Reporter: Leonid Ilyevsky
> Priority: Major
> Attachments: taskmanager.log.20200323.gz
>
>
> At some point I noticed that a few jobs got stuck (they basically stopped
> processing the messages, I could detect this watching the expected output),
> so I tried to cancel them.
> The cancel operation failed, complaining that the job got stuck atÂ
> StreamTaskActionExecutor$SynchronizedStreamTaskActionExecutor.run(StreamTaskActionExecutor.java:86)
> and then the whole taskmanager shut down.
> See the attached log.
> This is actually happening practically every day in our staging environment
> where we are testing Flink 1.10.0.
