I think the patch is in the > mainline kernel as well by now. There is still a problem with malloc. Malloc takes a unsigned int but the msb it discarded to safeguard against problems with signing. So, with Arcangelis kernel-patch mysqld can safely grow up to 3.5GB but no single buffer can grow beyound 2GB - as each buffer is allocated in one go (at least innodb_buffer_pool - which is the one I care about). I have not tried to remove limittation this due to lack of time and a proper test rig. Maybe someone at MySQL might give it a go? You probably have better "torture chambers" too. ;) -- Per Andreas Buer -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
