-----------------------------------
Summary: Possible Leak in GlobalWindows
Key: FLINK-7473
URL:
https://issues.apache.org/jira/browse/FLINK-7473 Project: Flink
Issue Type: Bug
Components: DataStream API
Affects Versions: 1.3.2
Environment: See attached project
Reporter: Steve Jerman
Hi,
I have been wrestling with a issue with GlobalWindows. It seems like it leaks instances of InternalTimer.
I can't tell if it's a bug or my code so I created a 'minimal' project that has the issue...
If you run the Unit Test in the attached and then monitor heap you will see that the number of InternalTimers continually increases. I added code to explicitly delete them.. doesn't seem to help.
If I comment out registerEventTimeTimer ... no leak :)
My suspicion is that PURGE/FIRE_AND_PURGE is leaving the timer in limbo.
