My Plex setup has been working great for many years now. I’m using Linux/Unraid/Docker and I mostly use the Apple TV client. As of about a week ago, I’m experiencing the following problems: My server will sometimes become unavailable for periods of around 30-60 seconds. I’ve confirmed this both o…

How large is your Plex database file? [image] Library.db size more than doubled in latest version Plex Media Server Server Version#: 1.41.7.9784 After cleaning up my libraries some weeks ago my library.db size used to be about 176 KB. I’ve only added about 10 TV episode…

When ChuckPA was running I think it said the two databases were around 300MB and 700MB, though I’m not sure if that makes sense given I have about 60TB of media in there. I’ll read through this thread and see if any of it applies, thanks for the suggestion!

Seeing the problem with direct streams with no transcoding happening, so unlikely this is related. It’s also happening way more often than any of my library scans. But thanks for the suggestion

Took a peek into the DB size thread and it seems like a very promising lead, it’s specifically calling out statistics which is also showing up a lot in my slow transaction logs. Will try to check that out tonight.

Digging into this now. ls -al output from my Databases folder: root@Bastion:/config/Library/Application Support/Plex Media Server/Plug-in Support/Databases# ls -al total 4633952 drwxr-xr-x 1 abc abc 1120 Jun 11 08:10 . drwxr-xr-x 1 abc abc 100 Oct 15 2023 .. -rw-r--r-- 1 abc abc …

I don’t think this is it, my statistics_bandwidth table isn’t very big and my overall DB sizes seem reasonable given the size of my library.

Just took about 10 seconds to start a stream and I got these logs: [image] No clue how I’m supposed to debug any of this with a closed system.

Tried turning off automatic library scans, still seeing slow transaction logs but it just made it 20 minutes without buffering, will report back if that actually fixes it (which would be bonkers).

Whatever’s going on has gotten worse and my server is now going hard down until I restart it (so remote users are also affected now). Automatic library scans disabled didn’t fix it.

Putting a Datadog synthetic on my server has revealed that whatever’s happening slowly increases the server’s overall response time (this is the status endpoint) until eventually it falls over and needs to be rebooted. This really looks like some sort of resource leak on the PMS side. [image]
