Hi All, I have been facing "GC Overhead limit exceeded" exception for quite a time with my flink program. In my flink program, I have created a session window with time gap of 10 minutes and I am performing some custom reduce operation using Window function. The current statebackend is File System. The program works fine for 15-20 mins and then fails with "GC overhead limited exception" . My understanding of flink is that, the task manager's memory will be released as soon as operation under window function will be completed. But then why I am getting this error? What should I do to avoid this?
