At least, that's how I interpreted the message. Given my interpretation, that seems like an overloaded setting. My mental model of running programs differentiates Ctrl-K and an error, so I expect the message box for Ctrl-K to be different from the error message box. Is that wrong? I'll set it to #t and try the simulation in DrRacket again soon-ish. (For now, I need to use the command line because this is for a paper that's due on Friday.) Thanks for your help!

I think that the only two explanations are that 'exit' was called or that your ran out of memory, but it may also be the case that you'd get a dialog with no explanation. This could happen with this program, for example: #lang racket (custodian-shutdown-all (current-custodian)) or this one: #lang racket (kill-thread (current-thread)) Or, it may be the case that you'd get a dialog with no explanation when you ran out of memory, if there's a bug (race-condition or something possibly). I don't see how you'd get the yellow/black warning message without getting a dialog, tho, unless you have that pref set. Not much help, I know. Sorry.

"720.77MB" is what I got after clicking the GC indicator. (Before, it was about 300MB.) There were no command-line messages from DrRacket. I don't think this is an out-of-memory problem. DrRacket has been good about asking for more during other simulations, my limit is set to 1024MB, and I really doubt I'm allocating a 304MB temporary object. I wrote a small program to print 600000 debug messages, thinking it was a limit on the number of lines in the REPL, and it ran to completion. For full disclosure: I paused and restarted DrRacket from the command line (fg; ctrl-z; bg) a few times while the simulation was running, so I could use my laptop unplugged without draining the battery. Besides running out of memory, what else could cause a program to halt with "Interactions disabled", and how can I avoid it?
