Thanks for the follow-up, I appreciate it! Could you confirm which version of Plex had the change? Out might be better for me to roll back until this is fixed?
I added a movie around 6am and now at 10:10am it still has not received metadata because the other cycle has never stopped. My CPU activity also has not let up either.

Thanks @sa2000 ! I had actually found the previous version that worked right before I saw your reply. Server Version: 1.12.0.4829-6de959918, which of course preceded the mentioned 1.12.1.4871.
I was on Beta (now removed), which is why I saw it happen a few releases ago (I had incorrectly thought it was 4, but it was only 3 versions ago). I have turned off updating for the moment. I can update to a new version at whatever time you would like, should you want me to test the fix
Thanks, and feel free to use me for any reference points. I am not very technical on this side, (networking and phones are more my deal), but I am willing to help as needed.
Made it near impossible for newly added items in other libraries to be found and matched
Bogged the CPU of the computer (Mac) down
Overall server performance was affected (searching, or loading a selected item took far longer than normal)
Received a number of âProblem Loading Dashboardâ errors (though a page refresh would load properly if the error occured
Only could be stopped by a Plex Server Shutdown, selecting âcancel sync scanâ or similar would only stop it for 1 second, and it would start back up again
I made a number of adjustments to the Agents, which of course had no affect

Yay!
That was my general theory, but I couldnât find the wording for itâŠ

I think Iâve seen discussion somewhere (couldnât find it in release notes) regarding scans of data being fixed where, after first scan couldnât find data, there would be no more scans. That was âfixedâ, so, Plex will continue trying to find the data.
Considering you have personal music/audio files that no data will ever be found for, I theorize itâs quite possible that Plex keeps trying anyway.

I believe that the statement listed is the âfeatureâ that in my case is acting like a âbug.â Meaning, they have built in what I am experiencing intentionally.
Itâs super easy of course to upgrade and verify, which I will do today, but I think I was on that version a few days ago before I posted. I had then dropped beta, and went with the stable release 4885, at the time of posting. This morning I rolled back to 4829, of which works at the moment. However, I could be wrong, so I am gonna run it through the ringer and see! I appreciate you following up for my benefit, @JamminR !
Oh wait, the beta has 4885 like stable does. Canât get to 4871, which further makes me think this is all intentional, and not a âbugâ in their eyes (which obviously it is).
sa2000âs the Pl-expert, team of one.
Iâm horrible at understanding logs, so rarely ask for them.
Oh, another potential I just thought of - Itunes may be making small changes, file locks, etc, to the same folders you have Plex scanning. So, if itâs not that latest âfixâ that broke you, it could be a combo of both the âfixâ and Itunes kicking off scans due to file activity. If you can even shut down Itunes from running (itâs difficult in Windows from my understanding, runs as a service), then you might try that if rolling back doesnât help.
(Not related to plex, but just showing that different apps do different things - I donât use Itunes, but use Steam, itâs almost always periodically doing something to my HD)
I have not used iTunes on this computer ever (ugh! I really donât like Apple anymore). And, all is super duper on 4829, so the mentioned #8282 is likely the culprit.
I donât think anything else is accessing the folders, since once the scan starts, it stops, and leaves the never-ending âdownloading metadataâ cycle to commence but never scans again. Meaning, #8282 starts and never stops. The scan was only the trigger to start #8282.

Just want to bring attention that I too experience the same symptoms and problem as detailed here: https://forums.plex.tv/discussion/315530/metadata-matching-every-scan-now
This happened to not just Music but Movies & TV shows as well for me. I downgraded to Version 1.12.0.4829-6de959918 as specified above and the behavior is back to normal. Please keep us updated on when a fix is posted.

I recall it was always done for TV Shows at the end of every scan to look for any unmatched items

Re-running a TV show library scan on my now downgraded version I can confirm thatâs true. I have very few TV shows so the extra matching/downloading only happens with two dozen or so items. The bug of extra matching/downloading just the Music and Movie library happening makes the server practically unusable though.
Yes, TV Shows have been like that for a while, but custom TV Shows arenât nearly as common as music, nor are the sizes of libraries usually similar. Plus, TVDB is good where Last.FM is a pile of stuff.
I also (personally) donât have a problem with movies, but I just donât understand why this needs to be a âfeature.â Itâs not hard to press Refresh Metadata. But itâs impossible to stop this #8282 Refresh. Really, this needs to be an advanced feature thatâs configurable. Iâm okay if itâs left as default, as long as I can turn it off to use Plex.
To reiterate, sorry for ad nauseum, but for me Plex is unusable in v.4885. Not due to dislike, but physically unusable.

Just to let the devs know: I have the same problem and it renders the Plex server unusable until a restart.
Just incase it wasnât clear, this is the same for me.
And maybe one more hint: When Plex starts constantly scanning and I edit a library, the language control on the library type screen is not usable since its empty. Restarting the server fixes it.
I had the same issue, until I enabled the Use embedded tags option for my music library. It looked like Plex took one more pass through all the music files and since then it seems back to normal - no more constant scanning and new items in any library are detected and matched almost instantly. Have not checked many music items in detail, but Iâd say it is worth a try.
Edit: Unfortunately it did not last and the constant scanning continuedâŠ
