Server Version#: 1.13.5.5332
Player Version#:
My music lib is shown as being scanned or worked on but I don’t see any status messages flowing in. The Plex process constantly uses about 12%-13% of my NAS CPU and is the highest resource using process.
Stopping the library scan via the client web GUI, doesn’t bring down the CPU.
I think I see this effect since the last update…
Any idea how to track down or find out what plex server is actually doing on my NAS?
See the QNAP FAQ on the site here and enable debug logging.
Yes, got debug logging enabled. Where do I find the log stuff?
Ok, got it at /share/CE_CACHEDEV1_DATA/.qpkg/PlexMediaServer/Library/Plex Media Server/Logs, but what now? Doesn’t seem to contain anything obscure…
One of the Plex gurus here will likely ask for it soon in this thread.
Post the log up here and we’ll take a look. 
Most of the time, when PMS keeps scanning over, and over, and over, is because it’s trying to match something which is poorly named or has conflicting embedded metadata. (tags)
Which log should I post?

Settings - Server - Help - Download Logs will package it all up for you in a ZIP file and gives me what I need to see.
Just attach the ZIP
Ah, cool. Didn’t thought about the HELP menu containing this function. Good to know.
Here we go. Thanks so far.
Please turn OFF Verbose logging. Whatever might have been in there for me to see was overwhelmed and flushed by Verbose mode output (only a 26 MB queue). Verbose is only used when absolutely needed. Initial diagnosis and most resolution only requires debug.
Please attempt again after forcing a scan of the media.
Sorry for the verbose setting. Here are the new logs. I run a scan but not the one to re-read all meta-data.

Even when I stop the current scan, because it seems to hang, the CPU utilization stays high.
Thank you for the logs.
Now for the bad news.

What top level directory (Folder) are you adding to your library? Are you adding /share/CE_CACHEDEV1_DATA ? If so, this is incorrect.
Please help me understand how you have your media organized. It is possible you have the wrong types of media in the wrong places. This will cause it to fail matching.
You mean the qnap MM share? I once activated it to check out the qnap apps but then decided to use Plex. So no problem to deactivate it. Would that help?
Is the qnap Codex Pack necessary at all? If not, I can remove them. I didn’t read anything about a possible conflict with Plex. In the past it seemed to work.
No, it’s pointing to the media folders. For music this is /share/CE_CACHEDEV1_DATA/qnap-familie/supersync/musik
I have music in one folder, photos in a different and movies in another. The don’t share a common parent folder like media or so . In Plex I just point to the according folder for the specific media type, when adding a new library.
@dane22 Thanks for the link, didn’t see this yet. Going through it.
Please follow @dane22 's advice over mine. He taught me how to spell QNAP 
So, I now did:
Stopped QNAP Music Station, deactivated QNAP MM bib, stoppend MM Streaming Add-On, stopped CodexPack.
Removed my Plex music lib and recreated it using the correct path to the shared folder: /share/CE_CACHEDEV2_DATA/qnap-familie/supersync
Removed all .@__thumbs directories
Let’s see how this works out…
The media scan for music now run the whole night and didn’t finish… still showing it’s running. But no status messages since several hours. And the scan is not complete there is about 75% missing. I see some messages like: “… for an item finished” - not sure if this “an item” is a problem?
I attach now the actual logs once again. Which logs are the interesting once to take a look at? And what to look for?
I downgraded Plex to the previous version without any success.
So I expect that some files, folder names etc. make problems. But I don’t know the cause nor which ones are the problematic ones. Any idea how to find out? Where to look at?
