> At the moment after 
> [-FLINK-13982-|https://issues.apache.org/jira/browse/FLINK-13982], when we do 
> not account for adhoc direct memory allocations for Flink framework (except 
> network buffers) or done by some used libraries used in Flink. In general, we 
> expect this allocations to stay under a certain reasonably low limit but we 
> have to have some margin for them so that JVM direct memory limit is not 
> exactly equal to network buffers and does not fail. We can address it by 
> introducing framework off heap memory config option.
