[Bug]: Cannot schedule new futures after interpreter has shutdown when OpenHands receives Ctrl + C #11364
Description
Is there an existing issue for the same bug? (If one exists, thumbs up or comment on the issue instead).
- I have checked the existing issues.
Describe the bug and reproduction steps
We are starting OpenHands in a subprocess via Python, with the command:
python -m openhands.core.main --config-file /path/to/config.yaml -t "<task>"
It is running inside a docker sandbox environment using the base image FROM docker.all-hands.dev/all-hands-ai/runtime:0.58-nikolaik.
When we send a SIGINT to the OpenHands process, I would expect OpenHands to be able to handle this gracefully, including saving the trajectory to a file. Instead, we get the error cannot schedule new futures after shutdown.
This means we completely lose the trajectory JSON file.
