# NousResearch/hermes-agent · Persist compression failure cooldown across restarts

## Open now

- Nothing open on GitHub.

These issues and PRs address a bug where the session hygiene compression failure cooldown was stored only in memory, causing the same failing compression to re-trigger after restarts. The work involves persisting the cooldown state to a database so it survives process restarts.
