how to test

• npm install
• npm start - to start pm2 in cluster mode with 2 instances
• npm stop - to stop pm2
• node index.js - to start app without pm2
• node test - hit page 100 times using ab(mac/linux only)

Observation

• On [email protected], pm2 cluster mode is acting very weird when hitting udp client code. First request is fine but pm2 is crashing without any error/warning and not recovering at all. Same usecase works perfectly fine on plain node.
