Thanks, Philip -- I've restarted the server. We need better monitoring for it, but I don't have the time to fix it at the moment.

It'd also be great for Racket in general to have better visibility into running programs to see what's going wrong with them in situations like this.


All I could see was an unresponsive service that hadn't logged anything for about a day that was using 100% CPU. What was it doing? No way to tell!

Erlang gets this right: you can connect to a running system and see what it is doing.

Does Chez have anything to contribute here? Could Racket-on-Chez help me diagnose a mysterious silent inert 100% CPU program?
