Hi, I will try that. Would it be better to use 4.10 and MySQL w. LinuxThreads instead? It's production databases that we run on the machine so stability is a must (yes I know - 5.2 isn't stable yet...) The reason why we decided to use 5.2-CURRENT was that the improved SMP support - which seems to still have some bugs?
