I'm not sure if anybody have this issue, but I am running some computer aided engineering analysis and when I run the same analysis in Windows, I know that the analysis doesn't require more than 70 GB of RAM. But here, you can see that not only has it consumed all 128 GB of RAM that I have installed on my system, but it is also requiring or using almost 100 GB of swap.

Any ideas on what I can do to try and investigate this further? This shouldn't be happening.
