# NousResearch/hermes-agent · Cron scheduled runs breaking due to stale module caches

## Open now

- Nothing open on GitHub.

These items concern in-process scheduled cron jobs failing with ImportError after extended uptime, apparently caused by stale sys.modules entries. The group includes a bug report and two related fix attempts addressing module cache isolation for scheduled runs.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 PR(s) closed without merging.
- A fix was merged to main in PR #99521. Verify it addresses your case.
- **Recommended:** read PR #99521 (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-99521`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `1.00`: 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

- #98976: Scheduled in-process cron fires fail with ImportError ('cannot import name X') after hours of uptime — stale sys.modules; manual lane unaffected
