>                 Key: FLINK-28024
>                 URL: https://issues.apache.org/jira/browse/FLINK-28024
>             Project: Flink
>          Issue Type: Bug
>          Components: Build System / Azure Pipelines
>    Affects Versions: 1.16.0
>            Reporter: Matthias Pohl
>            Priority: Major
>
> We observed several situations already where log files reached a file size of 
> over 120G. This caused the worker's disk usage to reach 100% resulting in the 
> worker machine to go "offline", i.e. not being available to pick up new tasks.
