java.lang.outofmemoryerror java heap space JMeter

I am encountering OutOfMemoryError in JMeter after running for a period of time.


This can be fixed by changing the parameter in Jmeter.bat or jmeter.sh.

The heap value needs to be increased. I tried increasing it too 2GB but it started giving me another error.

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
errorlevel=1
Press any key to continue . . .

So i kept it to 1 GB for smooth operation and even i removed unwanted listeners from it.

Listeners consumes lot of memory. So we need to be cognitive of them.
