I don't think there is enough information here to put 
a finger on your problem. For example, the code 
you give does not, as far as I can see, lead 
to the creation of temporary files, which are 
the subject of the error messages you see. 

I suggest that you get in touch directly with 
tech-support at StataCorp. I guess that they will 
want a fuller picture, including a full statement 
of the code you are using.
