@diymatt Thanks for sharing and that's definitely weird. What you're describing sounds like some kind of infinite loop.
Were you attempting to install before or after 3pm Eastern time? I'm wondering if a small change I made earlier introduced some type of unforgiving loop or if something screwy was happening before. Unfortunately I don't have a lot to look through to try and identify it what caused it but, it happening right when a test ran is a breadcrumb at least. If there's any other details you have, i'd be interested.
Obviously I don't want it crashing entire machines. It's probably worth me adding log files that persist so they aren't destroyed with a container.
