We were seeing strange errors talking about how we can listen for events further back than 24 hours.
The theory is that the network was done for a period of time but the process kept spinning holding onto the old block number.
When the network came back - the in memory block number is now > 24 hours old and the JSON RPC errors saying
you cannot go that far back in time
- and then it death looped because it keeps asking for the old block numberIf we get any kind of error asking for block data - let's exit and let systemd restart us to ask again - this should avoid the deadlock we were seeing in prod
