> I think it is caused by: [FLINK-12483]. The reason is that the
> {{BackPressureStatsTrackerImpl}} samples only the main thread. FLINK-12483
> introduced a separate thread for executing the sources in the mailbox model.
> It is similar to other old bug that concerned only Kafka source: [FLINK-3456]
