Sudden loss of folder hierarchy from TV dsplay

Hi - I've just installed Serviio 1.4 server on my new QNAP NAS (TS420) and Serviio Console 1.4 on my Mac OSX Mavericks (10.9.4) and it was all working fine. The console comes up, sees the server on the NAS and I tell it to start scanning the shared folders on the NAS. This runs for many hours and on my TV (LG 65LA970V-ZA) - under the Serviio high-level "Videos" folder, I can track progress through the various subfolders (Genres, Directors, Actors etc.) as the Metadata is consulted. So far, so good.

Everything looks perfect but at one point a suspicious message appears on the TV screen announcing that "4000 files have been scanned. Only "linked" devices can access them". Or something very similar to that. I'm not really sure what that message means but the console showed that the scan of the files and metadata was still continuing so I didn't pay it much attention. However, it was about that time when I first noticed that the Serviio display on the TV was not as it had been. Suddenly the display under the Serviio "Video" folder no longer contains any subfolders at all. Not one. There is only an "Upper Folder" pointer, nothing more.

I have tried restarting/rebooting all components. Eveything comes up without error, the NAS server icon is still there in my SmartShare window on the TV, but I cannot access anything through it now because there is nothing below the "Videos" folder, not even "Titles" or "Folders". The console continues to report that scanning is still running (in "Status Check") and the MediaBrowser interface confirms that this is happening correctly.

Anyone know what is happening here ? Any help would be much appreciated. Without access via the TV (which was working fine at first), I'm screwed.

Cheers.

Sounds like a limitation of the TV. I have read that some Samsungs are limited to 1000 files in a container, so maybe this is a limit on the LG??

Just an idea - try turning off all presentation settings other than "Titles" (assuming you don't have more that 4000 titles starting with the same letter) and seeing if that helps. If there is a refresh server capability on the LG you may have to do that. If that does help, start turning the ones you really want on one at a time.

This is working on the assumption that the limit is 4000 items in one container/category - if its an overall limit then it may be more difficult.

@DenyAll,

Well thanks for that. Your instincts were good and after extensive experimentation it does seem that there are undocumented arbitrary (very low) limits on how much metadata my (very expensive) TV can handle. It does mean that I now have to maintain two separate repositories on the SAN - a small one for Serviio (when I need strong subtitle support) and a big one for Twonky that has flaky subtitle support but doesn´t choke the TV with metadata. I did discover that the LG on-screen help facility advises not to put "too many" (!) files in any DNLA container which must rank as one of the dumbest and unhelpful pieces of technological advice I have ever received. I'll be writing to LG for poper details and a fix - if I get anything back from them worth knowing, I'll post it in the LG sub-forum. Thanks again.
