We will need more information to offer any solution. The exception
simply means that a TaskManager shut down, for which there are a myriad
of possible explanations.
Please have a look at the TaskManager logs, they may contain a hint as
to why it shut down.

Yes, to every node in the cluster.

Hi,
We had the same metaspace problem, it was solved by adding the
jar file to the /lib path of every task manager, as explained
here
https://ci.apache.org/projects/flink/flink-docs-release-1.4/monitoring/debugging_classloading.html#avoiding-dynamic-classloading
<https://ci.apache.org/projects/flink/flink-docs-release-1.4/monitoring/debugging_classloading.html#avoiding-dynamic-classloading>.
As well we added these java options:
"-XX:CompressedClassSpaceSize=100M -XX:MaxMetaspaceSize=300M
-XX:MetaspaceSize=200M "
From time to time we have the same problem with TaskManagers
disconnecting, but the logs are not useful. We are using 1.3.2.

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

I have seen this when my task manager ran out of
RAM. Increase the heap size.
flink-conf.yaml:
taskmanager.heap.mb
jobmanager.heap.mb
