I am getting a lot ECONNRESET
Error: socket hang up

at processTicksAndRejections (internal/process/task_queues.js:80:21)In one of my application sending request to my microservice. Both are running into my kubernetes and calling via the internal endpoint, for example my-service.production:3026
It happens when we are sending a lot of requests from the app to the service which is performing request into mongodb.
The problem is that on the app side I only have the ECONNRESET error and nothing on the service.
Can the issue comes from the kubernetes network ? And how can I debug it ?
With the looks of it, you are getting ECONNRESET because TCP/IP connection limit is breaching.
By default each server/machine allow 1000 TCP/IP connections. Maximum limit of connections is 65,535. You can increase these connections by following answer on this thread mongodb : Increasing max connections in mongodb
You need to increase connections limit on every server involved.
