After upgrading to Apache Flink 1.4.2 we get following errors every few seconds on one TaskManager out of 3.

The respective TaskManager disappears and reappears in the cluster but no job can be successfully run on it.

Trying to run a job on this TaskManager gives

Also the TaskManager seems to send no heartbeat response back to the JobManager

The cluster was recreated from scratch with the same results. This was not happening for 1.3.2

What can be causing this?

We did a couple of things here after the error disappeared:

We restarted the JobManagers

We increased TaskManager Memory size from 1GB to 2GB.

I can't explain it, but for now error is not showing up anymore since few weeks and all seems fine
