Hi,
We are running Gatling 2.2.1 release and see this exception for some simulations only (not always).
In the middle of the simulation is a frame referring to io.gatling.http.ahc.HttpEngine.warmpUp(HttpEngine.scala:96)
Could this exception be due to not being able to contact whatever URL is being passed into warmpUP method?
If so, is there a way to disable the warm up or point the warm up to a different URL?
Thanks
Sajjad
