Goodmorning everyone,  
I’m starting to use gatling and I found a strange behavior in analyzing my application.

I’m using this simulation class :

Executing the class (for more than 1 user), for the “cruscotto”, “doc emessi” and “doc suggeriti” request (are web service called from view with ajax) i get 302 HTTP result. Specifically, the application returns an “expired session” error. The odd thing is that only a percentage generates this error.

Is an access configuration error of my application?  
Or depends on wrong gatling configuration?
