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 at StreamTaskActionExecutor$SynchronizedStreamTaskActionExecutor.run(StreamTaskActionExecutor.java:86) and then the whole taskmanager shut down. See the attached log. -- This message was sent by Atlassian Jira (v8.3.4#803005)
