AbruptTerminationException in the Workflow Logs

[ruchim]

There's an Akka Streams AbruptTerminationException being thrown by some process being shutdown unexpectedly. It's not causing any actual issues for users, however it's presence in the log is distracting. We should make sure that whatever process is throwing this error should be shut down more gracefully.

akka.stream.AbruptTerminationException: Processor actor [Actor[akka://cromwell-system/user/StreamSupervisor-1/flow-6-0-unknown-operation#-1334744097]] terminated abruptly
[ERROR] [06/05/2017 16:56:14.156] [cromwell-system-akka.actor.default-dispatcher-37] [akka.actor.ActorSystemImpl(cromwell-system)] Outgoing request stream error (akka.stream.AbruptTerminationException)```

Hi guys, this is still happening in "cromwell-29". Just an FYI.

Regards.

@IsanEmory thanks for the update, that's good to know.
@ruchim can you tell me a bit more about what's going on to cause the message to show up?

There is an open ticket on the akka github for this: akka/akka-http#907
It's out of our control AFAICT. We've taken every precaution to shutdown things in order.

The message is harmless although confusing.
