Socket.io creates duplicate connections whenever the server restarts

[nitinankad]

Hi everyone,

I have a socket.io server and client for a chat room application and I'm running into an issue where the client connections are being duplicated whenever the server restarts. I'm storing users into a database for the chat room so that I can get active members and it's leaving behind stale records as a result of the server restart. I'm currently thinking of having an event listener for SIGINT and SIGTERM and cleaning up the stale records that way. Do I need to do anything special to clean up the previous connections?
