> When {{taskmanager.memory.off-heap}} is disabled, we observed that the total memory that Flink allocates exceed the total memory of the container:
> For a 8G container the JobManager starts the container with the following parameter:
> {noformat}
> $JAVA_HOME/bin/java -Xms6072m -Xmx6072m -XX:MaxDirectMemorySize=6072m ...
> {noformat}
> The total amount of heap memory plus the off-heap memory exceeds the total amount of memory of the container. As a result YARN occasionally kills the container.
