The system fixes this for you, but prints these warnings. There are some sysctl variables you can play with here. You can either just turn off the messages by setting machdep.unaligned_print to 0 or you can debug the problem by compiling MySQL for yourself with debug information and force it to crash. You force it to crash by setting machdep.unaligned_sigbus to 1. Printing these messages can also be turned off by setting unaligned_print="NO" in rc.conf. This is for 4.x btw. Not sure if these things works the same on 5.x. - IT Samo Jelovšek wrote: > hello, > > has anyone successfuly qualify MySQL on alpha?
