Node.js - Cluster Module

AAlways fork a new worker on 'disconnect' event

BUse cluster.isWorker to detect unexpected exits

CListen to 'exit' event and check if worker.exitedAfterDisconnect is false before forking

Solution:

Step 1: Understand worker exit events
The 'exit' event provides worker.exitedAfterDisconnect to distinguish exit types.
Step 2: Restart only if exitedAfterDisconnect is false
This means the worker crashed unexpectedly.

Final Answer:
Listen to 'exit' and check exitedAfterDisconnect before forking -> Option C
Quick Check:
Restart on unexpected exit using exitedAfterDisconnect [OK]

Quick Trick: Check exitedAfterDisconnect to restart workers correctly [OK]
