Javascript repeatedly crashes Max

Hello,

I have a patch that use an OCR program (tesseract) to analyze images culled from video. It is part of a larger patch that does all sorts of things with that data. It crashes fairly regularly (usually with 10 15 minutes of start but sometimes as long as an hour). I believe I have the crash isolated to the javascript that draws the text to the matrix "werds". If I disconnect this script the program runs for at least 24 hours. But I can't figure out what in the script (if anything) is making it crash. I have modified it (so you can use the text file I am attaching) rather than needing all the other third party stuff. I am including the other parts of the patch in case they may be causing or contributing to the problem.

Any help with this would be fantastic.Model Name:    MacBook Pro
