I am running OptionsSimulate.c to create options data for AAPL. I am getting the following memory error.
I tried doing the same thing with asset SPY, and it throws the same error.
My R, RQuantLib is installed correctly, verified with RTest.c

Any thoughts ?

That's a lot of contracts! I'm guessing you'll need 42 GB of RAM with a 64-bit Zorro to do whatever setup you had in mind. Plus Zorro is 32-bit, so that's impossible anyways.

What did you do?

I was running the script OptionsSimulate.c, changed StartDate and EndDate. The file is from https://financial-hacker.com/scripts2017.zip

Updated the script as below, its working okay now.
// StartDate = 20190101; EndDate = 20200630; -- this gave me memory issue
StartDate = 2019; EndDate = 2020;
