Changes
I noticed this issue with Akka.Persistence.Sql and will be sending a pull request for that as well, but TL;DR; we had some DNS issues that prevented Akka.Persistence from being able to contact SQL Server initially - this was caused by Kubernetes being slow to resolve a DNS route. The current design basically just kills Akka.Persistence and disallows it from restarting, requiring a restart of the entire process. There's no good reason for this - we can just restart the journal / snapshot store actors instead and give the process a chance of succeeding without a reboot.
