Crash to Desktop when batch processing in Scripts > Image Processing

I am running a job of over 6,000 files through menu item : Scripts > Image Processing  procedures that (1) read all files in raw format in a folder, (2) run certain steps stored in Action on each file and (3) convert them into PSD format.  It runs smoothly and successfully.  But, Photoshop force closed after finishing around 1,000 files.  I have to reconcile the completion list and the unprocessed ones.  Then, I re-run the remaining files.  However, Photoshop force closed randomly.  Is there a way to look into what issues caused the crashes?  Is there a way to prevent them?  I left the job running while I went out to work.  I did not want to see abended job after returning home.  Thanks,
