# NousResearch/hermes-agent · state.db teardown races and self-heal serialization fixes

## Open now

- Nothing open on GitHub.

Most members address concurrent access bugs around state.db teardown, cron worker lifecycle, and self-heal reopen races that could cause database corruption. One member is an unrelated whole-codebase refactor reducing source lines of code.

## TL;DR

- 7 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 3 merged PR(s), 3 PR(s) closed without merging.
- A fix was merged to main in PR #102117. Verify it addresses your case.
- **Recommended:** read PR #102117 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-104456`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.33`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #102827: \[Bug\] v0.21.0: #94736 self-heal reopen path can race concurrent writer threads → state.db structural corruption after cron teardown (NOTADB/malformed)
