## Problem We recently introduced log file validation for the storage controller. The heartbeater will WARN when it fails for a node, hence the test fails. Closes https://github.com/neondatabase/neon/issues/7159 ## Summary of changes * Warn only once for each set of heartbeat retries * Allow list heartbeat warns
