Server Randomly Shutting Down

Plex Media Server Desktops & Laptops
1

Server Version#:1.42.2.10156
Player Version#:4.147.1

My server, while watching, will randomly stop playing. I’m running Ubuntu 24.04.3 LTS.

I can ssh into the server, services are up, memory is good. But when this happens I can’t access Plex via web browser. It happens often, but I can’t for the life of me figure out why. Not sure what logs are needed. Attaching the log that was during the time of it freezing most recently.

Something tole PMS to stop.

I do see it completing an earlier crash report upload.

That was me, I restarted it to get it back working.

4

I think I’ll run your db repair utility because in looking at the logs I see it trying to hit my old xSteve server which I haven’t had in at least a year. In looking at the PMS settings I don’t even have the tuner setup in there.

This stopping of playing is very frustrating as I cannot pin down the cause. It’s so random

5

Anything in the crash report uploaded?

I ran your DB repair, I’ll see if that fixes anything:

I cannot see what’s in a crash report.
That info is stored in the cloud and only accessible by Engineering.

It did it again, at 3:26. I did not restart it and pulled the logs. Are you able to see what it might be?

So, I can access the PMS via ssh, but not via web…it’s the oddest thing! It pings, it’s almost like the webserver is shutdown

Memory looks good:

Services are up:

Odd thing is…I can’t see my storage,when running a df it freezes:

Minutes later it works

And then the server comes back up:

Here’s new logs after the server comes back up (via web):

@lance_mayfield

Looking at your logs shows no errors.

I see the server communicating with Plex.tv and being reachable (remote access)

I’ve had trouble with Plex/web when those long URLs are used.

If you strip everything after /web, does it populate ?

11

No, still not reachable. I discovered that my PiHole was not allowing local access so I resolved that.

It just shut down again and I’m think it has something to do with the mount to my NAS. I ran a dmesg and it looks like there’s issues with the NAS but I can access it from every other platform.

This isn’t new…I’ve had this setup for about 2 years.

13

If NFS isn’t responding, are you not allowing the NFS UDP/TCP traffic ?

14

Definitely something with my NFS mount, but I just don’t know what.

I mount at startup with: sudo mount -t nfs 192.168.1.247:/volume1/data /mnt\r

15

Why not set the mounts in /etc/fstab and let them mount by systemd at startup?

Here is my main NFS mount for backups

192.168.0.20:/vol/backup /glock/backup nfs defaults,sec=sys,rw,auto,async,rsize=4194304,wsize=4194304,x-systemd.after=network-online.target,nofail,bg 0 0

16

Well…I’m not blocking it that I know of. It wors, sometime for hours with no issue. Then, it just stops.

If I do nothing, it resolves itself in 10ish minutes

17

I can research that and try…think it would be better?

18

10 minutes is the retry interval.

Are you using standard MTU=1500 packets?

19

Yes, Ubiquiti DM pro, standard MTU

20

I would definitely look at getting things into /etc/fstab

/etc/fstab is processed BEFORE Plex and other system services start.
