Here's a screenshot with various diagnostic windows up. It looks like /dev/core is the culprit for me since my hdd is 1T but the process says it is 140.7TB in size, the link goes to /proc/kcore but using sudo rm /proc/kcore results in a message "Operation not Permitted" in the terminal. However sudo rm /dev/core works, and the memory drops to 20% of RAM for a few seconds then goes back up to 25% of RAM out of 8GB. I'm not sure what my next step should be since I deleted core and there is no bootchart.
