Server crashing - Windows Event Viewer shows ucrtbase.dll as faulting module

[CaffeinatedGuy]

Server Version#: 1.24.0.4897
Player Version#: ?? N/a but Plex Web is 4.59.2

This is my first time using these forums so please bear with me if I’m missing relevant info.

Relevant info from the most recent Windows Event Viewer log (today at 0422):

Faulting application name: Plex Media Server.exe, version: 1.24.0.4897, time stamp: 0x610818bf  
Faulting module name: ucrtbase.dll, version: 10.0.19041.789, time stamp: 0x82dc99a2  
Exception code: 0xc0000409  
Fault offset: 0x0009eddb  
Faulting process id: 0x2a38  
Faulting application start time: 0x01d78b32d858dcca  
Faulting application path: D:\Program Files (x86)\Plex Media Server\Plex Media Server.exe  
Faulting module path: C:\WINDOWS\System32\ucrtbase.dll  
Report Id: e67c5d76-2240-4f4c-9ab7-d3ec8724b6cf  
Faulting package full name:   
Faulting package-relative application ID:   

I ran sfc /scannow and it fixed errors, but the log didn’t have any mention of ucrtbase, and the issue returned this morning…

I don’t see how to attach files, so here’s the last 3 minutes of items from Plex Media Server.log

Also worth noting, but

%LOCALAPPDATA%\Plex Media Server\Crash Reports

contained one file at the correct time but was blank.

%LOCALAPPDATA%\CrashDumps

Contained a DMP file, but again I don’t see how to attach a file. I used Windbg Preview to analyze the dump file, and here’s the result.

ucrtbase.dll, version: 10.0.19041.789

That’s part of the Microsoft VC Redistributable package, and I believe that’s a current version. While it’s possible there’s a problem in the MS VC libraries, it’s more likely that it’s something in Plex or elsewhere on the system.

SYMBOL_NAME: plex_media_server!sqlite3_spellfix_init+10bb95

When this occurs, is the crash consistently in sqlite3_spellfix_init?

You can .zip up the .dmp and attach it with the Upload button in the forum - it might be worth waiting for a Plex person to respond.

[CaffeinatedGuy]

In reviewing the dump files and the event viewer, I’ve noted that this crash happens exactly every 3 days, starting 7/14/21, and occurs between 0200 and 0430. Given this, the next crash should happen on 8/10 if a solution is not found.

[Volts]

That sounds similar to the frequency of Plex’s automatic Scheduled Tasks. Are they enabled in Settings → Scheduled Tasks, and do those times match the schedule configured?

I believe that full-text indexing is updated during Database Optimization.

Does it crash immediately when manually optimizing the database? Settings → Troubleshooting → Optimize Database?

[CaffeinatedGuy]

Yes, scheduled tasks run between 0200 and 0500 every three days (I didn’t realize that, thanks!)

No, manually running “optimize database” does not crash the server.

The crash doesn’t seem to happen consistently in sqllite3_spellfix_init. I’ll post a couple dump files, but here’s a couple pre-analyzed dumps pasted below:

Was there ever resolution on this? My Windows 10 server is crashing every morning and it seems to be a similar issue as discussed here. I am running the latest beta server. Here are last night’s logs Plex Media Server Logs_2021-09-18_06-10-19.zip (3.1 MB)

[Alleyne1210_yahoo_com]

This is a plex compatibility issue with the windows ucrtbase.dll. try upgrading plex to version 1.24.2.4973, and as a secondary step run windows update to update windows as well. the first step alone resolved my issue.

[CaffeinatedGuy]

I’m currently running 1.24.2.4973 and per Event Viewer, my last crash was 9/15, which seems that the 3-day pattern has been broken.

I had implemented a workaround (I set Task Scheduler to start Plex server every morning) so I’ll disable that workaround and monitor for future issues.

Thanks for bringing my attention to the fact that this may be fixed.

[CaffeinatedGuy]

Update: Plex had crashed again this morning with Event Viewer again pointing to ucrtbase.dll

[spdelope]

I have involved @sa2000 here

Crashing repeatedly on 1.23.6.4881 Logs included

Server Version#:1.23.6.4881 Player Version#: n/a Plex Media Server Logs_2021-08-01_10-36-38.zip (1.7 MB) Since about 2200 cst my server has been crashing repeatedly. I have restarted the server a and app a couple times with no results. I turned off remote users and it has helped some but it is still mostly unusable. Windows 10 please help

Seems to be the exact same issue

[Corbo_Entretenimiento]

Any solution to this problem? … I have been with the problem of NAT: UPnP for months, I have changed the router, I have set a fixed IP, enabled ports, activated Upnp, deactivating, routing … dozens of failed attempts because the problem persists … it works good for a few days and then boom … again PMS starts to crash wit same ■■■■■■ line NAT: UPnP…

[spdelope]

This sounds like a different issue than what we’ve been having

[Corbo_Entretenimiento]

It’s the same record that CaffeinatedGuy exposed in the logs at the beginning of this post…

[CaffeinatedGuy]

I finally resolved the issue by unchecking “Refresh local metadata every three days”.

The issue Corbo_ describes sounds completely different. I’d recommend finding the frequency of the crash, looking into the crashlogs for more clues, and digging into log explorers. In my case, it was totally happenstance, but the biggest clue (that I failed to see) was that it occurred every 3 days, so it had to be a process that would run on every third day (minus restarts).

@spdelope

This sounds like a different issue than what we’ve been having

Thanks for the logs and database captures
I see the server is still crashing after high memory usage
Whilst the database is still showing the very high number of extras and trailers for 3 movies, i cannot confirm that this is the cause of the last set of crashes on the 2nd November that I looked into

I suggest we get these excessive number of extras purged and then see if the server is still crashing with high memory usage and then I can decide on next action. I have seen previous evidence of these movies actually implicated

There are 3 movies in the database with very high number of extras
The last time these extras were added was 31 August. So it is possible the cause has been fixed - I am not sure. Will need to be on the lookout for any new examples of excessive number of trailers added

It may take a few hours to get these purged
Suggest you start in reverse order - purging Gremlins first and leaving Star Wars movie to the last

To purge the extras, disable addition of trailers for the library and save
Then refresh the metadata for each movie
Starting with the Gremlins
It may take few hours for the Star Wars extras to be purged - you would be able to see the deletions in the Plex Media Server logs as it is doing - eg

This log extract from another user’s log shows the sequence that gets logged for deletion of each of these extras counted in the table above

Nov 04, 2021 13:59:50.532 [8832] DEBUG - Deleting media item 100834.
Nov 04, 2021 13:59:50.533 [8832] DEBUG - Was connected to metadata item 41719, count is now 2.
Nov 04, 2021 13:59:50.533 [8832] DEBUG - Updating deletion state for metadata item 41719, is has a dead item count of 0.
Nov 04, 2021 13:59:50.533 [8832] DEBUG - Deleting media item 100835.
Nov 04, 2021 13:59:50.534 [8832] DEBUG - Was connected to metadata item 41719, count is now 1.
Nov 04, 2021 13:59:50.534 [8832] DEBUG - Updating deletion state for metadata item 41719, is has a dead item count of 0.
Nov 04, 2021 13:59:50.534 [8832] DEBUG - Deleting media item 100836.
Nov 04, 2021 13:59:50.535 [8832] DEBUG - Was connected to metadata item 41719, count is now 0.
Nov 04, 2021 13:59:50.535 [8832] DEBUG - Destroying metadata item 41719 (Coyote Lake: Don't Try To Out Smart Me)

So with these extras purged, you can then re-enable the option to add trailers on the library and refresh the metadata for the 3 movies again

You could at this point take a snapshot of the debug server logs and the database

Then capture the logs again and the database on a weekly basis or on next crash and I will have a look if we are still getting the high memory usage and also see if there is any evidence of excessive number of trailers added

Thank you for all the diagnostics and help

[spdelope]

I have 4k versions of each of those. Are they the 4k or HD version?

Edit: nevermind. I found them.

[spdelope]

So I got through the first two, then on a new hope, PMS crashed after a couple minutes and then when I started it back up, that entry was deleted from my library

I did the Plex dance and it won’t add it back

Edit: hold that thought. I forgot to empty trash

Is there anything else in my database with, say, more than 100 extras? I would call that excessive and should be dealt with as well.
