We use the software on our home directory servers.  Our servers are hanging
when we do a drive scan and we have to disable the otg service and reboot
the machine to get it working again.  Also,  the software is generating alot
of error messages trying to locate files.  It seems to be a good product for
servers that don't change alot.  Our home directory servers continuely
change when users login and diskextender doesn't seem to keep up with the
changes very well.
