I think the issue has something to do with my machine running low on RAM. I've tried to run multiple instances of the script at once, but have had no luck.

There are more than 30 predefined data types that can be used in codefusion testing tool which will ease your work when it comes down writing scripts. I have found nothing particular about this software but if one want quality output then there should not find any problem at all.
