I am using the FreeTDS driver.  I will try a different driver/database
combination.  

Thanks,

 From a quick read, it looks ok, but it does depend on the driver as

When you have these sorts of problems, its often worth just trying the 
same thing with another database/driver to see if the leak remains.
