To address the subject line first: we don't have any fixed resource
limits in FOX. The problem that you're describing, however, is almost
certainly a GC-related bug in FXRuby. A possible workaround is to add
somewhere near the beginning of your program's execution. That won't
work around all GC-related bugs, but it often does the trick. And I
stress that it is just a work-around; we need to identify the actual

Repeatable bugs are good things. ;)
Can you send me a copy of the program and some instructions on how to
reproduce the crash? Even better, if you hit on a way to reproduce the
problem in a pared-down version of the application, that will reduce
the number of distractions during debugging.
