Hello Team, We have deployed a flink job in application mode using flink k8s operator. I see that flink job manager memory usage is increasing and reaching 95%. Heap usage of JM is around 60% though. What else could cause increase JM memory usage.

It looks like theres some debugging help on this page: https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/memory/mem_setup_jobmanager/#configure-off-heap-memory But to summarize:

There can be the following possible sources of Off-heap memory consumption:

- Flink framework dependencies (e.g. Akka network communication)
- User code executed during job submission (e.g. for certain batch sources) or in checkpoint completion callbacks

Thanks
