Stack-Heap Collision

I made a gazebo with a script to change the transparency of the dome and walls. Everyonce in awhile it sends me this message: "Stack-Heap Collision".

What does this mean and what should I do about it?

Means whatever you're doing requires more free memory than the script has at this point and so the operation fails. Though i was under impression this leaves the script in locked up state until it's reset either manually or by recompiling, or by another script. o.O;

You can avoid it by taking good look at your script and trimming or rewriting memory intensive operations (manipulations of large lists and suchlike) so they process smaller chunks or do things differently where possible. In worst case it may be doable to split the script into separate scripts which perform smaller tasks and coordinate through link messages and such...

Also check for recursion, ie a calls b, b calls a, ad infinitum
