ReadyNAS OS 6.1.6FINAL no ReadyDLNA after Cold-Start

On my ReadyNAS 102 v6.1.6, I've found that the DLNA checkbox becomes "unchecked" after reboot for (at least) external USB devices (I have 3 external disks attached). Ironically, DLNA clients are still able to access the NAS and stream video & music, as well as pictures. However, if while in this 1/2 working state I make changes to the NAS DLNA filesystem (add / remove files), those changes do not appear on DLNA clients and will produce an error if the file has been deleted or renamed. I think that the DLNA service continues to run but uses a "stale" index for those shares. If I check DLNA on the NAS, everything goes back to normal (well, it takes an hour to rebuild the index, which stinks, but I know I have thousands of files to index). If I then un-check DLNA, those shares no longer appear on DLNA clients.

I have another 102 running v6.1.4 and it also has a similar issue - DLNA checkbox becomes unchecked after reboot. However, DLNA clients cannot see any shares at all until the DLNA checkbox is checked and the index rebuilt. It seems there has been some change between these versions and it is improving.

I think Netgear would have a lot less to worry about if the darn thing would just spin down the disks (and CPU?) while idle.
