Server Version#:Windows 10 1903
Player Version#:1.18.0.1913
The past 2 betas have caused my Plex server to be unusable when scanning libraries. I have a rather large music collection and when Plex scanned the library it caused CPU to spike to 100% usage. It also knocked the server offline, showing “Unreachable” in the Web GUI. Once the scan completed it appeared to work again normally, and the server became reachable again… That is until I added rather large TV series collection and now it is doing the same thing. Is this really the future of Plex?
1.18 implements a new music agent. Since you have a Plex Pass, if you previously had a Premium Music Library, this would have gotten upgraded to the new system. The delay you saw could have been this upgrade. With a large music collection, this can take a while. If you are still seeing delays, it could also be it hasn’t finished and still upgrading. I’d say give it a few days to see if things settle down.
what I mean is, if any individual folder has (too) many files in it, it can currently cause a high cpu load, something the plex devs are aware of and investigating.
if you do not have any folders with hundreds or thousands of files in it, then this probably does not apply to your issue.
the new library conversion does use cpu to scan and process, so it could simply be normal until all that gets finished.
OK, I see what your saying. My library does not have any single folder that would have anything more then 60 items at the most. Everything is structured within subfolders, So say my Music library may have 135K songs they are all split into subfolders based on the structure I stated in my last reply. Would that still be the reason for the high CPU usage?
The Server is nothing special. It’s an i5 2400 with 16GB of ram. It’s been enough to do everything Ive needed of it with zero problems until this recent update.
I already have those setting checked to run as scheduled task. Which has me wondering why me adding the new TV show library caused this to happen as soon as it was added.
can’t say, but that is a pretty old cpu, and as previously stated the new music library conversion does take a fair bit of processing, so its possible that both the music process and adding a new show is simply overloading the cpu temporarily.
at this point, it is probably going to be necessary to have logs with the problem happening, so the devs can see plex is doing that may be causing the load.
if Plex Web is still accessible when you see the problem happening, you can download the logs @ settings > troubleshooting.
Similar issue here. Large music collection (+200k files), CPU @ 85-99% for days now which leads to plex web app not connecting to media server which in turn lead to not being able to change any of the settings mentioned above.
Finally managed to connect after several stops and restarts of plex.
I think “Analyze audio tracks for loudness” should definitely be off by default to avoid issues like this…
So I tried the update released today and it was no help. Until Plex gets this issue sorted out, which is pretty widespread from looking at Reddit and these forums, my solution was to roll back to 1.17.0.1841. CPU is back under control and my server is again reachable.
