# NousResearch/hermes-agent · Thread-safety fix for gateway progress_callback state

## Open now

- Nothing open on GitHub.

A bug report and multiple related fix attempts addressing unguarded shared state (last_progress_msg/repeat_count) in the gateway's progress_callback, which is called concurrently by ThreadPoolExecutor workers. The fixes add threading.Lock to protect that deduplication state.

## TL;DR

- 4 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 0 merged PR(s), 3 PR(s) closed without merging.
