detecting and reacting to a race condition/infinite loop

Is there a way to detect when an image has entered an infinite loop?  If
so could I then halt it, save the image, and reboot from a previously
known good configuration automatically?

I have a site with a weird bug on a remote server that has become
annoying to debug because when the infinite loop occurs the RFB process
becomes unresponsive.

Or maybe I should stop running headless temporarily and use X forwarding
through SSH.

Anyways, is there a way to detect an infinite loop an react to it?



Thanks

Hi Paul,
and everytime you made a coffee and then you went back to your computer
it has rebooted, since the ui-interface noticed it was in an infinite
loop waiting for your input <g>.
but its generally not really possible. consider an object that has a
variable i and these 4 methods:
Counter>>initialize
i:=0

Counter>>inc
i:=i+1 \\ 42

Counter>>count
200 timesRepeat: [self inc]

Counter>>dumb
[self inc. i<50]whileTrue

it would not be sufficient to store the state of _all_ variables, the
moment one var changes, it would not be sufficient to store the state of
the program at this moment (iow that it is in method inc when i gets set
to the same value), you would also need to store the history of the
program states (iow that it comes from method dumb).
