### SUMMARY run-server.sh launches gunicorn without exec, so when the script is the container's entrypoint the shell stays PID 1 and gunicorn runs as its child. A container's PID 1 is only sent a signal if it has installed a handler for it; the shell installs none for SIGTERM, so the SIGTERM delivered on `docker stop` / Kubernetes pod termination never reaches gunicorn and gets SIGKILLed when the grace preiod expires, dropping in-flight requests on every restart and preventing graceful rollouts. ### TESTING INSTRUCTIONS ### ADDITIONAL INFORMATION Fixes #41172 - [ ] Has associated issue: - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Migration is atomic, supports rollback & is backwards-compatible - [ ] Confirm DB migration upgrade and downgrade tested - [ ] Runtime estimates and downtime expectations provided - [ ] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
