AccessViolation in ntdll.dll on Windows XP

I have an AIR application that loads a series of html components and rotates through them, showing a component while reloading the next one, then showing the next one, etc. It works fine on every OS (Mac, Windows 7, Vista) except on XP it sporadically crashes with a c0000005 AccessViolation in ntdll.dll at either 7c91b121a or 0001b21a. The program actually continues to run just fine while the report an error dialog displays. Sometimes the problem happens within 5 minutes of starting the app; other times, it can run for hours with no problems. This is happening on many different XP machines, mostly running SP3.

I don't know much about debugging, but I did catch the error using ntsd -g and have pasted the output below. If anyone has any suggestions of other commands to run to get more information, I can recreate it and post more info.

I really appreciate it if anyone can help me out - this one is driving our entire team crazy.

Thanks,

Brian
