---------------------------------------
Summary: Taskmanager dies after job got stuck and canceling fails
Key: FLINK-16728
URL: https://issues.apache.org/jira/browse/FLINK-16728
Project: Flink
Issue Type: Bug
Affects Versions: 1.10.0
Reporter: Leonid Ilyevsky
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.
