### What happened? Hi Beam community, I am using Flink 1.19 + Beam 2.61.0(via FlinkRunner) to process data. But I notice that the memory usage on workers (Flink task managers) keep going up linearly v.s. time. An eventually OOM. I believe Beam should flush data from memory to disk at the end of each bundle, so I try setting `max_bundle_size=10` and add logs to `start_bundle()` and `finish_bundle()` of my DoFN's. But the memory usage still accumulates and the logs in `start_bundle()` are printed only once and logs at `finish_bundle()` is never printed. So you have idea what may be the issue? Thanks, Muyang ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [ ] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Infrastructure - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
