Hi, all!
I am currently conducting a stress test of the application.
This is to check the critical point of how many requests the server can withstand.
The api request scenario sends a simple post request.
You’re running into local ephemeral ports starvation.
First, try tuning your OS: https://gatling.io/docs/current/general/operations/#os-tuning
If you still hit limits, consider going with distributed load tests with FrontLine.
