InDesign crashing when running script on large files

Question

Hello,
I have created a javascript that will:
For each InDesign file inside of a specified directory {
Open the file
Find all textual elements with the specified character style
Convert that textual element to a hyperlink
Export the file to PDF (with a specified export preset)
Close the document
The script is working great. However, the script will cause InDesign to crash if it encounters a file with a larger file size.  The script works fine with InDesign files that are less than 50 - 60 MB.  When it hits a filesize that is any larger, InDesign will crash. I am running InDesign CS5.
Does anyone have any recommendations?
Thanks!

I figured out my problem:  I had a block of code in my for loop (which converts all character styles of a given name to hyperlinks) which would set the hyperlink styling properties.  For some reason, this code would crash InDesign when dealing with larger InDesign documents.  I deleted this block of code from my script.
Here is the code block:
for(/* looping through the active document */){      .     .     .      ++hyperlinks;
     with(hyperlink) {
          highlight = HyperlinkAppearanceHighlight.none;
          borderStyle = HyperlinkAppearanceStyle.solid;
          visible = false;
          name = foundTexts[i].contents + " :" + id;
Thanks for everyone's suggestions!
