OC Evolver Restart Loop Fix

Symptoms

• service stuck in activating/auto-restart
• logs show Singleton ... already running repeatedly
• restart count increases continuously

Root cause pattern

• stale lock or PID reuse causes false "already running" detection
• service policy restarts even on benign exits

Procedure

1. Inspect service state and restart counters.
2. Inspect lock file and verify process identity.
3. Patch lock guard to verify real Evolver process identity.
4. clear stale lock and restart service.
5. Re-check status + restart counter stability.

Output

• Root cause analysis
• Patch summary
• Stability proof after fix

Safety

• Keep changes minimal and reversible.
• Redact infra and identity details in external artifacts.
