A critical issue has been identified in the Monitor Service background thread where an IllegalStateException is being thrown continuously.

Error Details:

• Error Type: java.lang.IllegalStateException
• Error Message: "monitor failure"
• First Detected: 2025-05-21T15:10:00
• Last Detected: 2025-05-31T00:15:57
• Occurrence Count: 25
• Error Score: 75 (High)
• Error ID: b2f3824a-3655-11f0-bc70-ca59c7e8e81d

Root Cause:
The monitor() method in MonitorService was directly throwing exceptions without proper error handling or state validation, causing the background thread to fail repeatedly.

Resolution:
A fix has been implemented in PR #82 that includes:

1. Circuit breaker pattern to prevent cascading failures
2. Proper error handling with retry mechanism
3. Health check functionality
4. Fixed isRunning() method
5. Added diagnostic logging

Impact:
This issue was causing the monitoring service to fail repeatedly, potentially missing critical system health checks.
