Reader Error when trying to replicate to backup db

[tomfriedhof]

Describe the bug I tried to replicate a new database after an initial application boot. The application sets up several streams on boot to populate general configuration for the application. After everything is initialized, and after I have verified the application is working as expected, I run the replicator to mirror the db to another EventStore instance. The replicator gets to 95% complete and then produces a read error:

}

To Reproduce Steps to reproduce the behavior:

1. Boot up the application, and allow all setup streams to be appended to log. Verify application is working.
2. Run the Replicator to copy db events to another instance
3. Unable to finish replication due to a read error

Config/Logs/Screenshots The logs from the replicator prior to the error look like this. It seems to be something with reading the stream metadata:
