Unable to open more than one instance of JMeter
Hi,
I have a machine with 160 GB of RAM, where in the Heap space settings in
JMeter was done as below (100 GB allocated).
set HEAP=-Xms102400m -Xmx102400m
However, I'm not able to open more than one instance of JMeter, getting the
below error,
Error occurred during initialization of VM
Could not reserve enough space for object heap
errorlevel=1
Press any key to continue . . .
Please let me know on what changes needs to be done to make it work.
Thank you,
Muthu.

Hello,
Please give us the Java version / provider (and I suppose that is a 64
bits version)
jmeter.log shows some messages?

Sure you can't. You need 200GB+ of RAM for that.
Try 2 JMeter instances of 70g first and try increasing towards 80g.
