Hello,

I would suggest you to increase the maximum heap size of the JVM to 1536m.

In gatling.bat, find the "-Xmx1G" parameter and replace it to "-Xmx1536m". In the latest release, it is on line 45.

Hi Stephen, many thanks for your quick reply. The application is launching now :-)

Now I am getting this error..

The application launched once only after setting the switch -Xmx1536m in gatling.bat

[chandra shekhar Turha]

The machine I am using is 32-bit

[chandra shekhar Turha]

I tired setting ENV variable, but no luck

Variables->New: Variable name: _JAVA_OPTIONS

Variable value: -Xmx1536m

[Barry Perez]

A 32-bit jvm supports a 1.5gb heap.

How much free memory is there on your machine before starting Gatling?

Please tell us you've checked this?

[chandra shekhar Turha]

it is less than 400MB

[Barry Perez]

There's your problem then...

[Senthilchandrasekar Thangaraj]

I have 67.8GB free space in my machine.

but it shows
