Subject Re: Re: java.lang.Exception: TaskManager was lost/killed

I've seen similar problem, but it was not a heap size, but Metaspace.
It was caused by a job restarting in a loop. Looks like for each restart,
Flink loads new instance of classes and very soon in runs out of metaspace.

I've created a JIRA issue for this problem, but got no response from the
development team on it: https://issues.apache.org/jira/browse/FLINK-9132
