I am supporting a ColdFusion 8 website running on Windows Server 2003 R2 (with all Windows Security Updates applied). The website functions smoothly 99.9% of the time. However, about 2 months ago, the ColdFusion 8 Application Server service started crashing and restarting itself every night at 10:30 PM. There is a ColdFusion Scheduled Task that runs at 10:30 PM every night, so I tried running it manually (direct URL in a browser), and sure enough the ColdFusion 8 Application Server service crashed and restarted. So, it's obviously this one template that is causing this to happen.
What this template does is read a directory full of PDF files, then loop through those files to create several thumbnail images for each using CFPDF. This Scheduled Task has been running for years without this issue. The CF service appears to be crashing/restarting almost immediately, before a single file is processed.
I tried running the same template in our Staging environment, and it ran fine - no CF restart. I'm very confused.
Searched through the ColdFusion logs and found nothing.

Thanks to @MarkAKruger for pointing me to CFROOT\runtime\bin\hs_err_pid*.log files. It looks like a memory issue when trying to convert the PDF to PNG....
Here is a link to the contents of the file from the last time I tried to run this template (to large to include here):
I would still really appreciate any help figuring out how to fix.....
