---------------------------------
Perhaps cc [~pnowojski]~
With the findings when debugging
https://issues.apache.org/jira/browse/FLINK-18356:
1. The reuseForks are set to false for flink-test module, indicating it should
not related to other issues.
2. One possible issues might still be the network buffers could not be
deallocated in time. For this case, each test would create separate
mini-clusters and create network buffer pool, and the buffers in the pool would
only be deallocated on the direct buffer get GCed.
