Plex Media Server update 1.18.7.2438 hanging

Which seemed to alleviate the instant crashing occuring when some clients tried playback. But today I checked on the server and it seemed to be “Scanning” a Library, and being stuck forever on it. I tried closing Plex from the task bar, and its stuck in some god forsaken deadlock it seems. I can’t end task Plex Media Server.exe, nor multiple instances of Plex Media Scanner.exe

I sent you in a PM @sa2000 new dump and log.

Thank you for the logs and dumps. The 2nd dump file was 0 bytes size - but it does not matter - sounds same issue as in the earlier set of diagnostics

It appears that some scanner processes are hanging overnight when running analysis / metadata refreshes as part of scheduled tasks. So we need to look into those by getting files that the scanner hung on and then see if it can reproduced and referred to the development team

There appears a second issue in that on exiting Plex Media Server, the attempt to kill and terminate those Plex Media Scanner processes does not seem to work and database locks remain stopping shutdown from completing

When this happened and you took the process dump, did you notice 3 Plex Media Scanner.exe processes still running in task manager in first case and 4 processes for the 2nd ?

You could filter the Windows Application Log for events 1000,1001 and see if there were any Plex Media Scanner.exe exceptions

Is this Windows 10 ? or Windows Server ?

I have sent you the paths for the media files that the scanner jobs were stuck on

So if you can get me these files - and send me link by private message, I will see if I can repro the problem

There was also a hang when starting to process this directory

F:\tvshows\Brooklyn Nine-Nine\Season 7

In case I cannot replicate, the next time this happens and you have scanner processes hung from many hours before, you could after securing all the logs, force process dumps for the scanner processes that are stuck

This tool may be useful in finding out what files are locked out (open) by each process - OpenedFilesView - View opened/locked files in your system (sharing violation issues)

Just plain Windows 10.

I’ll try to get the files to you today.

Yes when those crashes happened I tries end tasking PMS and noticed there were multiple PM scanners running , and attempted to end task them which did not work.

All of these crashes make the computer unable to “software restart” , that is , Windows never manages to close them to be able to reboot. Which is terrrrible since I often can only remotely manage the server.

That sounds like a windows issue - windows not able to close down processes would explain why Plex media server could not either

What is the F Drive ? Any entries in the windows system event log relating to it ?

Thanks for your PM. So you got a hang similar to what the scanner was encountering when attempting to copy these files. Sounds like disc drive issues but I would expect that there would be some windows event log entries within the SYSTEM event log for any disc I/O errors. Or may it just hangs. What is the F Drive? Internal / external ?

Suggest running an integrity check and also surface read scan of all blocks and any other system tests available from the drive manufacturer
