I have  checked that there are no tables associated with any user in tempdb. Any help is appreciated.

Answer 1

this basically is a re-write of an existing stored procedure that will show
temp tables in the tempdb, and their relative size. I also have a query to
show the size of tempdb in MB that i used with this one, it is also a modification
to an existing system stored proc that shows allocated and free space in MB.
