Steve Jerman updated FLINK-7473: -------------------------------- Attachment: timerIssue.zip Sample project showing the issue. Look for org.apache.flink.streaming.api.operators.InternalTimer in heap and you will see it continually grows. Steve > 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 > Attachments: timerIssue.zip > > > 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. > Steve -- This message was sent by Atlassian JIRA (v6.4.14#64029)
