sqldf returns Error: database or disk is full

Would you care to elucidate at all?? I was under the impression those warning messages are expected for commands that return no data. Or are you talking about something else m

I'm using sqldf() to execute a query using a named dbname.? It appears to create an external db but after 30 minutes or so returns:

Error: database or disk is full
The disk is not full, so have I hit some internal db size limit?? The external db created is about 610MB and doesn't grow, so maybe it's running out? of room for the result set, where ever that is stored?

Code being executed is:
