Existing delivery servers fixed, the start-up script has been fixed for all new servers, and failed deliveries are retrying.
We will continue to monitor until errors are retried and delivered.

Confirmed the problem was error connecting to chef server on start-up, which should prevent the delivery processor from starting to take on delivery jobs, but did not. Working on retry failed deliveries, and fixing the root cause.

Initial investigation is that delivery server did not configure itself correctly on start-up, may have failed to connect to master configuration server (chef server).
