Problem Description

After upgrading to OpenClaw 2026.4.5, several CLI commands hang indefinitely without producing any output. The commands cannot be interrupted with Ctrl+C and must be forcefully terminated.

Affected Commands

• openclaw devices list
• openclaw pairing list
• openclaw sessions cleanup --fix-missing

Environment

• OpenClaw version: 2026.4.5 (commit 3e72c03)
• Node.js: v25.8.2
• npm: 11.11.1
• OS: macOS Sequoia 15.4 (Darwin 25.4.0 arm64)
• Hardware: Mac Mini (Apple Silicon)

Steps to Reproduce

1. Upgrade OpenClaw to 2026.4.5
2. Run any of the affected commands (e.g., openclaw devices list)
3. Command hangs with no output
4. Press Ctrl+C — does not interrupt the process
5. Force kill required (kill -9 or terminal close)

Expected Behavior

• Commands should complete and return results
• If stuck, Ctrl+C should allow graceful interruption

Actual Behavior

• Commands hang indefinitely
• No error messages or output
• Ctrl+C ignored (SIGINT not handled)
• Process must be forcefully terminated

Additional Context

• This behavior started immediately after the 2026.4.5 upgrade
• Previous version (2026.4.4 or earlier) did not exhibit this issue
• Gateway appears to be running normally (openclaw gateway status works)
• Only certain CLI subcommands are affected

Possible Hypothesis

• New CLI architecture in 2026.4.5 may have changed signal handling
• Commands may be waiting for a resource/lock that never releases
• Long timeout without user feedback or cancellation support
