title: Error message from worker: generic::aborted: SDK harness sdk-0-1 disconnected
body: <p>I am having some issue with one of Dataflow jobs. From time to time I get this error messages. It seems that after this errors, the job keeps running fine, but, this night it actually stuck, or it started to slowly process the elements.
  Also you can see from the screenshot that the workers started to behave very weirdly as shown in the CPU usage chart in the below screenshot.</p>
