You need to put it at the end of the transactions from your Web server, even if the Web server only did a select and didn't modify anything. I had the same problem you're having, and found I wasn't using the commit after I did a select. Adding $dbh->commit() as the last thing the persistent Web client does, in all cases, fixed it. -- Robert L Mathews, Tiger Technologies ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
