As you suggested, I went there and found 5 files dating back to Nov, 
2013, the most recent being yesterday.  They are all identical:

I understand that I can delete them, but how can I stop them from 
happening and giving all the errors.  My machine has slowed a lot 
recently, and I attribute it to all of these errors.
