Hello,

I am using gatling to put some static load on ur backend. Here is my snippet:

_setUp(_  
_scn.inject(_  
_constantUsersPerSec(rps + 2) during duration,_  
_).throttle(_  
_warmUp ::: List(_  
_jumpToRps(rps),_  
_holdFor(duration))_  
_).protocols(httpProtocol)_  
_).maxDuration(duration)_

The issue is related to throttle. It is working well in functional way i have constant rps but problem is with long tests, after arround 2 hours, despite the load. After this time i am start to recieve exceptions like java.lang.OutOfMemoryError. I think it is related with numbers of users, it is grows along the time which in my opinion cause issues with memory. Any idea how to dispose users? What I am doing wrong? i am attached image which shows signifacnt grow of active usrers.

Regards  
Marcin
