All we do is selects, there are no inserts/replaces/updates going on, during a backup The whole table has to be locked so you get a consistent state for the table. Not sure why you're only seeing this after your upgrade though. My understanding was it was a read lock, so concurrent selects would still work Do you have any stored procedures? I wonder if any bugs were fixed regarding those. I could select my_procedure(); and it does an update of a table's view count or something (think forum post views type scenario). -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
