mod_c2s_conn_throttle: Reduce log level from error->info Our general policy is that "error" should never be triggerable by remote entities, and that it is always about something that requires admin intervention. This satisfies neither condition. The "warn" level can be used for unexpected events/behaviour triggered by remote entities, and this could qualify. However I don't think failed auth attempts are unexpected enough. I selected "info" because it is what is also used for other notable session lifecycle events.
