# NousResearch/hermes-agent · Bounded graceful shutdown timeout for SIGTERM handling

## Open now

- Nothing open on GitHub.

These issues and pull requests address a problem where the serve backend process hangs or becomes orphaned when receiving SIGTERM, due to an unbounded graceful shutdown in uvicorn. The proposed fix adds a timeout to the graceful shutdown path so a single SIGTERM can reliably terminate the backend.

## TL;DR

- 6 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 4 PR(s) closed without merging.
- A fix was merged to main in PR #128336. Verify it addresses your case.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-128336`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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.
