Memory leak when using anonymize proxy

[Radonirina Maminiaina]

Hello,

I'm using proxy-chain to my proxy rotation, and worker_threads to manage parallel crawling, and pm2 to start my server with proxy-chain.
It is possible that many workers perform many tasks in some minutes and it brokes the operation.
When the crawling app runs and use proxy-chain for many hours, I have the error below:

(node:31706) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 error listeners added to [Socket]. Use emitter.setMaxListeners() to increase limit

How can I fix this?

Node: v14.x.x
OS: Debian
