# NousResearch/hermes-agent · Unbounded cache growth from credential/endpoint rotation

## Open now

- 1 issue, 2 PRs open on GitHub.
- #130241: \[Bug\]: \`_endpoint_model_metadata_cache\` is never pruned, so every rotated credential leaves a permanent entry
- PR #130245: fix(agent): prune endpoint metadata cache entries
- PR #131451: fix(cache): bound the credential-keyed process caches (rebase of #130664)

These items address caches that grow without bound when credentials or endpoints rotate, leaving permanent stale entries. The work involves bounding or pruning the affected caches.
