Some of the calls to job.SubmitAsync() result in the following exception.

Exception: System.InvalidOperationException: An error occurred while processing this request. ---> System.IO.IOException: Unable to read data from the transport connection: The connection was closed.

This error occurs on a daily basis. The current work around I'm using is retrying. Any idea what is the root cause?
