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 On Mon, Apr 9, 2018 at 11:36 AM 王凯 <wangka...@163.com> wrote: > thanks a lot,i will try it > > 在 2018-04-09 00:06:02，"TechnoMage" <mla...@technomage.com> 写道： > > I have seen this when my task manager ran out of RAM.
