nginx-clojure is not receiving cookies/header if many workers are spawned

nginx-clojure is not receiving cookies/header if many workers are spawned.
We have a scenario when we set workers more than 20, some of the request are missing auth cookies.

This is load test setup where many users are generating load to the live system.

I have done a simple load test and it got no error. The test used

• 25 worker processes
