The dreaded PARM error - discuss experiences and resolutions

Question

Hi all,
I'm having problems with the PARM error which I have found several discussions for. There never really was much of a solution other than avoiding "poorly written scripts".
So, after upgrading everyone to CS5,applying all CS5 updates, and making sure none of my scripts have any variables declared outside of a function scope the PARM errors still occur. I even tried creating a 10GB scratch disk for AI to use instead of the Windows boot disk and that didn't matter.
an Illustrator error occurred: 1346458189 ('PARM')
This can occur just once and not occur upon retrying the operation or it can start occurring for every script execution which forces the user to restart Adobe Illustrator. It doesn't consistently occur in the same place or the same script and seems to occur more often if users are creating complicated Illustrator documents with many objects.
Has anyone ever discovered anything particularly illuminating about these issues? Has Adobe support been of much help in resolving this problem?
I'd especially like to find out if Adobe ever provided some sort of debug utility or special setting that would provide more (ANY!) information regarding the specific cause of a given occurrence of the error.
I know that while Adobe Illustrator, or likely ANY CS5 application, runs there is a single continuous session for JavaScript operations. Eventually this seems to get some sort of condition that causes the error until it is closed by exiting all Adobe applications.
Here's my situation:
I have a set of rather complicated scripts being used with Adobe Illustrator which are driven by a web application, Microsoft CRM. I was really hoping that CS5 would resolve the problem since CS4 wasn't ever even patched but, while the frequency of the PARM errors has been reduced they are still an issue.
The scripts generate AI files from configured products in order entry. Options are picked from template files which can be rather large and placed in their appropriate positions on the final AI document. Custom artwork, logos, etc., are added to the mockups, printed to the pdf, attached to an email, and then sent off to the customer for approval. Layout documents are also generated for screen or label printers.
Here's how my scripting is handled in general:
1. The main body of each scripted action is stored in the database; attached to the approval document template which serves as the base of the document which will be sent to the customer.
2. When an action is triggered from the web application, i.e. create document, snap to/resize customer artwork, fill in order text, etc. the body of the script for the requested action is retrieved from the database.
3. Each script contains a function that serves as the starting point of the operation. This will take one or more parameters usually consisting of custom objects and strings.
4. A "main()" entry point function is generated and has no parameters of it's own. The generated main() function contains declarations of any parameters that are passed to the function for the specific operation which was retrieved from the database.
5. The full text of the newly generated script is executed in Adobe via a custom ActiveX control I created, MSCRM only works with Internet Explorer, using the JavaScriptIllustrator.DoJavaScript method.
6. An integer result code is passed back indicating success or failure. Any error messages are displayed within the scripts themselves using JavaScript alerts.
Here is an example of how my scripts are organized in case anyone can spot an issue. The main() function is generated so there aren't any indentations, etc.

Additional note:
I test scripts using the ExtendScript Toolkit editor using copies of scripts from running the scripts in debug mode. Doing this I can occasionally reproduce the error without even going through the ActiveX control and just manually running scripts in the ExtendScript Toolkit editor.
So, the problem doesn't have anything to do specifically with being executed from a web application.
At any rate I can't reliably reproduce the PARM error under any circumstances. It just appears to occur randomly.
Edit: pressing TAB to hide all of the desktop items such as the layers list, colors, etc. had absolutely no effect.
