Issue Description

After migrating from Z2 Mini to Z8G4, the Chrome profile locks when Chrome crashes on Z2 Mini, causing "profile in use" errors on Z8G4.

Steps to Reproduce

  1. Run OpenClaw on Z2 Mini with Chrome open
  2. Machine loses network or Chrome crashes
  3. After restarting on Z8G4, Chrome refuses to launch due to stale SingletonLock

Expected Behavior

Chrome should either clear stale locks automatically or provide a recovery mechanism.

Proposed Fix

Consider adding auto-detecting and clearing stale locks on startup.

Original Context

Originally reported in #75330 (event loop blocking issue related to browser startup failures).

extent analysis

TL;DR

Implementing auto-detection and clearing of stale locks on Chrome startup is likely to resolve the "profile in use" errors after migrating from Z2 Mini to Z8G4.

Guidance

  • Investigate the feasibility of adding a mechanism to automatically detect and clear stale SingletonLocks when Chrome starts, as proposed in the issue.
  • Review the event loop blocking issue related to browser startup failures in #75330 to understand potential connections between the two problems.
  • Consider implementing a recovery mechanism that allows Chrome to handle stale locks gracefully, such as prompting the user to restart or providing an option to override the lock.
  • Verify that the proposed fix does not introduce any security vulnerabilities related to profile access and locking.

Example

No specific code example can be provided without more context on the Chrome and OpenClaw implementation details.

Notes

The effectiveness of the proposed fix may depend on the specific implementation of the auto-detection and clearing mechanism, as well as any underlying issues related to the event loop blocking problem.

Recommendation

Apply workaround: Implementing the proposed auto-detection and clearing of stale locks on startup seems to be the most direct approach to resolving the issue, given the information provided.
