Hi Guys,
I am running into memory issues running my script with version 2.0.0-RC2
My simulation is running from a Windows 2008 server virtual machine.
During test execution heap usage keeps increasing up to a point CPU usage goes through the roof and my tests fails.
My scenario looks like this:
setUp(scn.inject(constantUsersPerSec(1) during (600) // warm up of the SUT
,rampUsersPerSec(1) to(150) during(3600)
,constantUsersPerSec(150) during (172800))).protocols(httpProtocol)
Some relevant script information:
The script uses ELFilebodys with are fed with values from a number of feeders.
val httpProtocol = http
.baseURL(“https://some-host.com”)
.acceptHeader(""“application/soap+xml, application/dime, multipart/related, text/*”"")
.acceptEncodingHeader(""“gzip, deflate”"")
.userAgentHeader(""“Mozilla/4.0 (compatible; MSIE 6.0; Windows NT)”"")

I can share a heapdump and the full script with you via dropbox if you like.
Any help is appreciated since I’m trying to convince my management to use Gatling as a replacement for LoadRunner 
Cheers
Daniel
