I know the MySQL folks found from bitter experience that MacOSX can be just as annoyingly painful in its behaviour as other platforms.. This is from the MySQL 4.1.9 release notes relating to InnoDB (where they need some way of making sure data hits disk for ACID compliance): http://forums.mysql.com/read.php?3,11554,11554 InnoDB: When MySQL/InnoDB is compiled on Mac OS X 10.2 or earlier, detect the operating system version at run time and use the fcntl() file flush method on Mac OS X versions 10.3 and later. In Mac OS X, fsync() does not flush the write cache in the disk drive, but the special fcntl() does; however, the flush request is ignored by some external devices. Failure to flush the buffers may cause severe database corruption at power outages. -- Christopher Samuel - (03) 9925 4751 - Systems Manager The Victorian Partnership for Advanced Computing P.O.
