> 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.
