That's 16GB of swap space! I was lucky to get a screenshot.

*edit* PERHAPS this was an honest incident and the process wasn't killed when the student hit ctrl+alt+backspace or something...it appears to have been running for 72 hours and I still dont know exactly how they would have managed this...I didn't notice any other machines like this (didn't look either), so it may not have been a remote/network render. There's no harm done here if it was unintentional...
