Ubuntu 18.04.2 LTS - Plex Server Crashes - Double free or corruption (!prev)

Plex Media Server Desktops & Laptops
1

Server Version#: 1.15.1.710
Player Version#: Many/NA

I keep getting crashes that state the error in the title. The service however still shows it is running. A restart fixes it for a few days but it’s annoying as service checks still report running so I don’t know it’s crashed unless I go to watch something or a user reports that it is down. I tried doing a check/repair of the database following all the steps on the Plex KB regarding that and the issue is still occurring. Googling that error without Plex referenced seems to indicate it’s a programming/memory error. Is there anything I can do to prevent this or is it a matter of waiting for the dev team to identify the bug and fix it?

Edit: forgot to mention, server is an Ubuntu 18.04.2 VM with 12CPU/8GB Ram running under ESXi on a Dell R710.

Here is the service status

Please clarify,

Freeing a free memory block or freeing a free disk block ?

3

I’m not sure what you mean?

Edit: The VM has plenty of Disk and Ram resources.

4

There are two different free() system calls:

  1. When an application is done using memory and gives it back to the OS (free up memory)
  2. When a file is deleted and the space it previously occupied is placed back on the free-block list.
5

I’m not sure how to tell which it was? The issue seems to happen every couple of days.

6

When it happens, do you restart only Plex or do you restart the OS (guest)?

If you restart only Plex, we go one way.
If you restart the Guest OS, that is entirely different.

If the Guest OS, I first suggest a routine forced integrity check of the file system (better safe than sorry) .

Since I’ve not seen this elsewhere yet, when you have time, give memtest86+ a spin and let it run the suite just for peace of mind.

7

I only restart Plex with

sudo systemctl restart plexmediaserver

I’ve had no other odd behavior with any other VMs (10+) on the host so I don’t imagine running memtest would reveal anything. Would also be rather hard to do as I’d have to shutdown my host for multiple days for it to scan all 96GB

8

Excellent!

The next time it happens, please do this as quickly as possible.

  1. Settings - Server - Troubleshooting - Download Logs
  2. Upload the ZIP file it gives you here so I can see the errors.
9

Will do, it may be hard for me to do it immediately after it happens as I sometimes don’t know for hours since service checks still show “running” however when I looked at Plex Media Server.log earlier it had not incremented anything new in the 5 hours since it crashed. When I choose download logs does it remove usernames and such from it? I’d rather not post that information as accessible to anyone who wants to look.

10

You can increase the number of logfiles retained if you want.

  1. Stop Plex
  2. Edit Preferences.xml
  3. Add LogNumFiles=“20” (or whatever you want up to about 50) right before the trailing />
  4. Save it

Make sure you are DEBUG logging only so as not to lose it to VERBOSE mode (keep verbose off)

11

I’m having the same issue recently. I’m using docker for my plex, but every 7-10 days it seems to crash with the same error as the title.

The dmp file for the crash report is completely empty

12

I can’t help with Docker (zero familiarity with those runtimes and how it’s configured).

Another thought I had was the EAE codec itself might have a problem.

This said, rename it and force it to download a fresh copy.

This will eliminate or prove the EAE is the source of the issue

13

Where would this EAE codec be located? I’m assuming the process would be stop Plex > rename the codec to .orig etc… > start Plex and it will re-download the codec?

Also, will downloading the logs strip any identifying user information?

14

/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Caches

15

I do not appear to have anything EAE there?

I found these should I rename the two Linux ones?

17

rename -OR- I thought of this too:

  1. Make a .hold subdirectory
  2. Move all of them into .hold

That will hide them just as well.

18

I moved them all into /original/ and only one was created upon restarting the service. Will see how things go and report back.

19

That makes much more sense. There was no legitimate reason to have the Windows executables there on a Linux system.

20

I migrated my server from Windows to Linux about 6 months ago is probably how they ended up there. Should know in a few days if this fixes it or not.
