kws.unsubscribe(instrument_tokens)

You need to use ws.unsubscribe(tokens) to unsubscribe required token/list of tokens.

@rakeshr i am not unsubscribing inside a callback if that is what you are referring to . but in a separate function which is being called by another py importing 'myticker'

@chaklin
You need to paste the WebSocket code, for us to debug this further. From the above stack trace, it looks like you are not calling unsubscribe method properly.
