Your Plex server is creaking—here are 3 signs it's time to start over

If you've been using Plex for years, there's a good chance your server is getting a little creaky. You've added and removed thousands of videos, there's junk metadata gunking up your database, and some stuff doesn't work right even though you're all up-to-date. Is it worth troubleshooting these issues individually, or is it more time efficient to just burn it all down and start with a fresh server? That depends on the details because, as the saying goes, that's where the devil is. Any changes you make to Plex files, like its core database file, should only be done while the server isn't running! Your database is damaged, and recovery hasn’t worked All your database are belong to us As you can probably deduce, Plex stores all the information about your media library in a database. If that database file (it's called com.plexapp.plugins.library.db) is corrupted for any reason, then you'll either see a messed-up database, or you'll get just errors. This can happen for a variety of reasons, including the common cause of all file corruption—disconnecting a drive while it's writing data. However, a buggy Plex update, malware, or really any other potentially destructive computer accident can be behind the issue. Obviously, it's important to deal with the root cause of the file corruption (e.g., replacing a bad drive), but assuming that's sorted, how do you deal with the corruption? If you have any sort of recent backup that happens to include that database file, you can, of course, just overwrite the corrupt one with a backup of the last known good version. Failing that, Plex offers its own tool called Plex SQLite, found in the Plex server installation folder. The database repair process is lengthy and involved, but Plex has a complete official guide, which should always be up-to-date for the latest version of the application. If your efforts to restore or repair your database are unsuccessful, then you don't have much choice but to start fresh. However, you should also weigh up the time and effort of repairing versus just wiping everything and setting up a new server, especially given that success is by no means guaranteed. The server keeps crashing or running out of memory Getting too big for its britches Credit: Lucas Gouveia/How-To Geek If your Plex server keeps crashing or getting "out of memory" errors, that could be a sign of an issue that takes so much effort to diagnose and repair that it might just be easier to start from scratch. A corrupt database is one of them, but if it's not your database that's corrupt, you can, of course, preserve it and import it to your new server installation. Common reasons why this happens are fancy features like opening and credits detection, sonic analysis for music, or big transcoding jobs, especially if you're not paying for hardware acceleration. If you're using an old mini PC like I am with limited RAM and CPU resources, it's probably better to turn some of those RAM-hungry features off. If your Plex server isn't dedicated but also runs other tasks or is used for other work, then those competing applications could also be cause for a lack of resources. GPU drivers, Windows updates, antivirus scanners, and so many more things can be behind this sort of software instability too. If you're not up to sniffing out the exact issue, a clean slate might be just the ticket. There's no fixing this match Setting up the files and folders for a Plex library is trickier than it sounds. If you follow our tips on organizing your Plex library, then it should be smooth sailing. However, years ago, none of us knew what we were doing. To be fair, Plex is largely not too bad about automatically figuring out what stuff is, even if it's been named poorly. Also, if you take the time to fix the data of new content as you add it, it doesn't become an insurmountable job. Plex only lets you fix metadata one title at a time, in which case you might as well wipe your database, go fix the folder and name structure of your media files, and then have it just do it all right in the first place. You can save some stuff Assuming that it's not the root cause of your issues, you can actually back up your Plex database and support files. This will preserve your metadata and watch history. It's the process documented in the Plex "Move an Install to Another System" documentation. The only difference is the target computer is still the same hardware, just with a freshly scrubbed brain. If you try to import your old database and support files into a fresh Plex installation and the problem returns, your only real option is to try those database corruption fixes I mentioned above. Failing that, you're better off starting everything from scratch and setting up a pre-emptive Plex backup so you can just roll things back if they go wrong. Then again, it really isn't that much work to just set everything up from scratch, and this time maybe use something like tinyMediaManager to properly sort the metadata instead of letting Plex do it.
