Plex Server Stops Responding But Process Still Running?

[dbowles1975]

Server Version#: 1.28.0.5998
Player Version#: 4.84.1

PMS running on an 11th gen i7 NUC. Recently migrated install over from an older PC. Used the directions here to the letter. No issues after migration. The issue popped up a few versions ago. I had a hard time installing the upgrade because it kept telling me there was an upgrade even though the version numbers were the same. I had to do a manual install to correct that. The last info in the server logs just before the server stops responding looks like this:

Those same or similar entries had been repeating over and over for at least ten minutes before the server stopped responding. This seems to crash about every 12 hours or so.

Sounds like the deadlock issue that has been affecting multiple people. See this thread here: Plex Server Crashing Randomly - #78 by brucestephensrx

Looks like the deadlock issue we are investigating. An alpha 1.28.1 build is being tried by a number of users. I see that you are now on the 64-bit windows forum preview release which is also on 1.28.1 - so hopefully that will fix the problem - if not, we will need to get deadlock diagnostics which you can find in the linked topic or can be explained when seeing full debug server logs of the issue on 1.28.1

Will this 1.28.1 version be available for Windows beta users ?
Plex is crashing every day with the current version.

Plex is crashing every day with the current version.

If you want to verify you have the same issue, take a look at this post and PM the diagnostic info to @sa2000 so he can add you to test builds:

Plex Server Crashing Randomly

I think that the issue that I am having is what is called a “deadlock”. Plex icon stays active in the system tray, but when I try to open the Plex web interface nothing loads. The clients are unable to play anything from the server as well (local and remote). I found an old post from 2018 solving an issue called “503 Service Unavailable”. To everyone else here experiencing the issue first verify that the Plex icon is still in the system tray (Windows). Here are the diagnostic steps outlined by @…
