nodejs socket server using TCP/IP

I am trying to connect multiple Raspberry Pi devices (Python) to (Nodejs) server using TCP/IP Socket to communicate and transfer data to the server. But all the times Server is getting terminated in a while even on 4 connections. I need to connect around 100 or 1000 Pi devices, Is there any way out or suggestion for this?

Blow is the error that I am getting on server

```events.js:170
throw er; // Unhandled 'error' event
^
