Monitor Service IllegalState Exception Critical Failure-created-by-agentic

[shaykeren]

Issue Description

The Monitor Service is experiencing critical failures due to unhandled IllegalStateException occurrences. This is causing service disruption and needs immediate attention.

Impact

• Critical service failures (priority score: 95.0)
• Multiple occurrences between July 12-13, 2025
• Affects the MonitorService$_$monitor endpoint
• Service reliability compromised

Root Cause Analysis

1. The monitor() method is throwing IllegalStateException without proper monitoring logic
2. No retry mechanism for handling transient failures
3. Poor thread management implementation
4. Missing health checks
5. Incorrect isRunning() implementation

Solution

A pull request has been created that implements the following fixes:

1. Proper monitoring logic with health checks
2. Retry mechanism for transient failures
3. Improved thread management
4. Robust error handling
5. Fixed thread lifecycle management

Verification Steps

1. Deploy the updated service
2. Monitor for IllegalStateException occurrences
3. Verify health check endpoints
4. Test retry mechanism
5. Validate thread lifecycle management

Additional Notes

The implementation has been updated to be more resilient and includes proper error handling and monitoring capabilities.
