The specific error is related about database replication: "Replication wait failed: MySQL server has gone away". There are other errors on this banner that seem linked to rebuilding the Translate extension MessageGroupStats index. See these Logstash entries.

There's a possibility that this would be solved by the translation-related patches made for T203925 but not yet deployed. However, since we're in code freeze, with year-end FR banners going up soon, I'd suggest we hold off on deploying them unless really necessary. @Seddon have you seen this come up again? If it's happening often, we could still try deploying those.
