Also, is it OK just to delete browse through the UI and delete old snapshots manually?

Yes.  Though personally I found that to be tedious to maintain, which is why I recommend using custom snapshots with limited retention.

"allow snapshot access" was checked on most shares. So I have unchecked as per you recommendation.

 

I had another period of 6 hours of disk thrashing earlier in the week. At that time there were log references to possibly corrupt video file. The full set of errors is

Unfortunately no filename is mentioned. Is it likely this is in one of the other log files?

Did you see other timestamps, or only 03:58 and 03:59?  If this were the cause of the thrashing, you'd expect to see timestamps covering the full 6 hour period.

There was a debug toggle for DLNA in OS-4 systems, but unfortunately that was dropped with OS-6. 

One option (tedious) is to create a temporary share, and move half of the media files into it.  Then rescan.  If the problem disappears, then the problem is with one of the files you moved.  If you repeat that process, you can narrow down the number of files that might be the cause, until you find it.

This looks like it might be an mpg2 dvd rip, which might also help narrow it down.
