Currently, I have 9 instances running for my NodeJS backend, and I suspect that this might be causing performance issues or preventing some requests from being processed properly. Despite having multiple instances, I am experiencing situations where the server does not respond to requests, as evidenced by the lack of response logs.

I want to know whether these 9 instances are causing any issue because I am having issues in some endpoints that server did not responded with any statusCode or response time as shown in the given endpoint.
