Assignee: ramkrishna.s.vasudevan
> Off heap memory deallocation might not properly work
> ----------------------------------------------------
>
> Key: FLINK-4094
> URL: https://issues.apache.org/jira/browse/FLINK-4094
> Project: Flink
> Issue Type: Bug
> Components: Local Runtime
> Affects Versions: 1.1.0
> Reporter: Till Rohrmann
> Assignee: ramkrishna.s.vasudevan
> Priority: Critical
> Fix For: 1.1.0
>
>
> A user reported that off-heap memory is not properly deallocated when setting
> {{taskmanager.memory.preallocate:false}} (per default) [1]. This can cause
> the TaskManager process being killed by the OS.
> It should be possible to execute multiple batch jobs with preallocation
> turned off. No longer used direct memory buffers should be properly garbage
> collected so that the JVM process does not exceed it's maximum memory bounds.
