Hi again... I've discovered (or perhaps re-discovered) what seems to be a memory leak involving temp tables. It's so bad that I make a script (which runs as a daemon) close the backend connection and reconnect each time it runs the offending command sequences. Without the reset I've seen the backend grow to over 100 megs in size in a matter of a couple of minutes. I've created a sample case that reproduces the error that I will attach with this message. Basically, I create a 50 column temp table (with no rows in it) and then run updates on each column in succession. The backend gets large pretty quick - I'm seeing about 12Megs after running the enclosed script which does an update on all 50 columns 3 times (150 updates). Thanks... - K Kristofer Munn * KMI * 973-509-9414 * AIM KrMunn * http://www.munn.com/
