The problem is most likely the loadbalancer- working with old data, even if the server is not needed, generates lag warnings for some complex dependency of how lag check works (generating 40K logs per minute). Abandon ship- this is not going to work, and nothing that wikibase developers or DBAs do can fix it.
Although you could do a new database requests every 10 minutes or so to mitigate that. Kill the process and restart it so it reloads the new config.
We currently run the dumper instances for about 1h... would it be helpful to shorten this to maybe 30m?
It will definitely help, but it may still get into race conditions, but obviously less than if it is every 1h :-)
