Katalon Parallel execution

I am using Katalon 6.1.4

While Parallel execution if we select > 10 instance Katalon not able to handle it. Showing execution error.

Could you please suggest how can I increase instance > 10 in Parallel execution.

Could you please let me know how many instance katalon can handle in Parallel execution.

Thanks.

you may have to increase the java heapsize allocation.
check your katalon.ini file and tune the values for Xms and Xmx
