Spongebob created FLINK-25373: --------------------------------- Summary: task manager can not free memory when jobs are finished Key: FLINK-25373 URL: https://issues.apache.org/jira/browse/FLINK-25373 Project: Flink Issue Type: Bug Components: API / Core Affects Versions: 1.14.0 Environment: flink 1.14.0 Reporter: Spongebob Attachments: image-2021-12-19-11-48-33-622.png
I submit my Flinksql jobs to the Flink standalone cluster and what out of my expectation is that TaskManagers could not free memory when all jobs are finished whether normally or not. And I found that there were many threads named like ` flink-taskexecutor-io-thread-x` and their states were waiting on conditions. !image-2021-12-19-11-48-33-622.png! -- This message was sent by Atlassian Jira (v8.20.1#820001)
