Hello,

I’m setting up Gatling on my laptop, i have been following the Quickstart guide and I have managed to record the computerbase scenario.

When I come to launch gatling.bat from the command line i get the following:

C:\Users\xxxx\gatling\bin\>gatling.bat  
GATLING\_HOME is set to “C:\Users\xxxx\gatling”  
JAVA = ““C:\Program Files (x86)\Java\jre1.8.0\_101\bin\java.exe””  
Error occurred during initialization of VM  
java.lang.OutOfMemoryError: unable to create new native thread  
There is no simulation script. Please check that your scripts are in user-files/simulations  
Press any key to continue . . .

GATLING\_HOME appears to be set correctly  
JAVE\_HOME appears to be set correctly

Anyone any ideas?

I’m using a windows 10 machine and i’ve downloaded Gatling 2.23

Any help is much appreciated.

No enough available memory on your laptop (because of other running apps?).

Hi Stephane,

The only thing i have running is the command prompt, memory is at 30%, when i start gatling.bat it peaks to 32% so that does not appear to be the issue.

you should increase java heap memory. try to execute using maven plugin and set jvm settings there.
