# NousResearch/hermes-agent · Preventing concurrent writable database opens causing corruption

## Open now

- Nothing open on GitHub.

These issues and PRs address a pattern where multiple components open the session/state database with write access simultaneously, which can trigger concurrent full-text-search rebuild corruption. The work focuses on making secondary openers read-only to ensure only one writable owner exists at a time.

## TL;DR

- 5 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 3 PR(s) closed without merging.
- A fix was merged to main in PR #108076. Verify it addresses your case.
- **Recommended:** read PR #108076 (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-108076`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.40`: 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.
