### Version
My brokers are using version 2.8.0.7 and there are three of them, used for handling delayed messages. Last night, due to a hardware issue, I restarted one of the brokers. As a result, all the messages that were supposed to be consumed by that broker on that day were re-delivered.

Contributor guide
Research direction
Start by reproducing the broker restart scenario described for version 2.8.0.7 with three brokers handling delayed messages, then trace how consumed-message state is retained across a restart. Done means messages already consumed by the restarted broker are not re-delivered; the issue names no files or tests to target.
