I've seen that with SMB mounts occasionally and it's driven me nuts. It seems only a reboot clears it. I haven't seen it since 10.4.8, but I don't know that that is relevant. I haven't really tracked it, and it could be that it hasn't happened since an older rev. and I just didn't notice when it stopped. Now for the real fun - another thing that can keep a volume busy is a long write. Basically put, if a long write is done to a volume, but the buffers have not yet been synced to the disk, the system will see the volume as busy but no actual files will be open on the disk. Usually this occurs if a vast quantity of data is being written to the disk amd the writer takes an interrupt, and the interrupt routine closes the files and expects to be able to unmount the volume. Depending on the timing, you may find your unmount failing with an EBUSY for no (apparently) good reason... This email sent to site_archiver@lists.apple.com
