The system encountered a socket close event, causing it to go "headless," meaning it could no longer communicate properly. The closure of the Master socket led to the PFE thread being stopped, and without a soft restart enabled, the FPC terminated its own operation ("suiciding").

Loss of communication and halting of the PFE thread, resulting in FPC shutdown.

Identify the Cause of Socket Closure:

• Investigate logs to find the root cause of the socket close event.

Ensure Proper Socket Handling:

• Verify correct socket management and error handling configurations.

Check System and Component Health:

• Review the health of the PFE and other critical components.

Consider Network Redundancy:

• Implement redundancy to maintain communication during socket issues.

Monitor for Recurrence:

• Monitor the system for similar issues to ensure proper resolution.
