Hello all, I am doing Windows testing on Katalon. I have a project in progress, but Katalon often crashes seemingly randomly, and I can’t figure out why. Usually, I would simply copy some files over into a new project which doesn’t crash (because the crashing is specific to opening a certain project), and continue working from there, but it has occurred so many times that I have to figure out what’s going wrong.
This time, every time I open this project and open a file (e.g. keyword or test case), Katalon immediately crashes. I don’t understand what’s failing, but they do create an error log file which is unreadable to my untrained eye. I’ve uploaded it on this post and really hope someone can help me decipher this.

From the log provided:
VMWare virtualization detected
CPU:total 2 (initial active 2) (2 cores per cpu, 1 threads per core)
Memory: 4k page, physical 8387408k(3519660k free), swap 9698128k(4347556k free)

Are you running this in a VM?
Katalon is sometime resource hungry, so you can try to allocate more resources to your virtual machine and further tune the settings for JVM (Xmx and Xms values) in your katalon.ini file accordingly to allocate more memory.
Looks like Katalon crashes due to an OOM kill.

For reference, here are my Hyper-V settings. I had no need to adjust the JVM memory settings. Note the uptime: ~25 days.
Well, I suppose you are using Katalon cleverly and you don’t create heavy usage projects, which may not be the case for @souptester …
I can create a demo project to crash Katalon very easy 
Just a recursive call test case
