You want me to send my logs to you?

Olli · April 3, 2022, 11:47am

No, not me.
Is’s just a known Problem on Windows-PMS.
You can switch the thread and ask @sa2000 or wait for a new build 1.26.1+ next week.

Zildjian91 · April 3, 2022, 11:51am

Ok, thanks for the help. Hope they fix it next week.

Hello,

So I wrote a PowerShell script for this issue as it was happening on my server and I thought I should share it.

$Process = Get-Process -Name "Plex Media Server" -ErrorAction SilentlyContinue
If ([string]::IsNullOrEmpty($Process)) {
    Start-Process -FilePath “C:\Program Files (x86)\Plex\Plex Media Server\Plex Media Server.exe”
}

Then I setup a scheduled task to start running at midnight and run every 5 minutes after that. The action/program powershell with the arguements “-file “C:\Scripts\Check-PlexRunning.ps1” -ExecutionPolicy Bypass”.

Not a perfect solution but since my server seems to die in the middle of the night this script/setup keeps it running and the only thing the end user might see a error saying error retrieving this content or whatever and if they try again it will start right up without issue.

Any questions let me know.

sa2000 · April 4, 2022, 8:47am

I have included you in the private message thread that will give you access to development build 1.26.1.5712 - which is looking good so far

Billy2025 · April 4, 2022, 2:32pm

I have been experiencing the same for the past week myself. @sa2000 can I get the development build 1.26.1.5712 as well?

Krashkource · April 4, 2022, 2:43pm

I have the same issue and after running the .dmp file through WinDpg preview app I was able to get the following info. I hope this helps for correcting the buffer overrun detected by Windows. Oh and just to note this is Server 2012 R2 not Windows 8.1 running my current server.

Same here, every night, between 21h and 23h GMT, my plex server closes itself since the last update, Versión 1.25.8.5663

frankkasten · April 5, 2022, 2:31pm

Same for me. Where’s fix?

Olli · April 5, 2022, 3:41pm

while it looks good, hopefully tomorrow when @sa2000 is back.

meanwhile you can try to disable maintainance jobs (daily / 3 days) until the new release is there.

EAGLEi222 · April 5, 2022, 4:03pm

This has happened to me now two days in a row and I see I am not alone.

Glad to hear a fix is in progress

2ndreality · April 5, 2022, 6:30pm

I’m having the same issue, good to hear it isn’t just me. Have used Plex for years now, this issue is sudden with the current build.

sa2000 · April 6, 2022, 7:42am

All

I am pleased to say that the fixes in development release 1.26.1.5712 that have fixed the Plex Media Server crashes with 0xc0000409 in ucrtbase.dll have now been ported back into the 1.25.9 beta and the release of 1.25.9.5721 made available yesterday has these fixes

Release Notes:

Fix for Window related EventSource crashes (#13437)

markus.will · April 6, 2022, 9:21am

Nice to read. A quite fix fix.

But… when trying to update no newer version than 1.25.8.5663 is found - nether at my local Plex nor on your download page. When will it be available for common?

sa2000 · April 6, 2022, 10:30am

very soon - may even be today.
Currently beta only for Plex Pass users

tom9933 · June 13, 2022, 2:12am

I’m still having what sounds like a similar issue and I just checked, my Windows 11 server is running Version 1.26.2.5797. I assume I should have the fix?

sa2000 · June 13, 2022, 7:49am

That specific crash has already been fixed. Is this happening on both servers or just the windows PMS ?

I cannot see any uploaded crash reports for your account

Best to get debug server logs captured after one of these crashes and if it is on windows, then look into the %TEMP% directory for dump files created at the time of the time of the crash - the filenames will not have any file extension and will have a name of random characters with dashes

dhomas · August 31, 2022, 4:56pm

I just saw what seems to be a similar crash this morning after updating to version 1.28.2.6151 yesterday.

I recognized it right away since I was also getting this issue before the patch and my last crash was on April 4th on version 1.25.9.5673, right before applying the fix.

Today, on version 1.28.2.6151, I got a similar crash with “code c0000409” on ucrtbase. Might it be regression on the previous fix?

Here is the analysis of today’s dmp file:

They are not quite identical, but similar enough that it made me think of this thread.

I have the entire dmp file, if helps, though I don’t know if it contains any personally identifying information.

Also, if I should create a new thread for this, let me know. Thanks for any help!
