Roon on Debian Linux Problem

Kevin_Mychal_Ong · April 5, 2022, 7:38am

Well, it’s been running alongside Plex for more than a year now without any issues. I’m also seeing others say the same like this post here. Also, I have the DLNA server in Plex disabled as I don’t use it so it shouldn’t be listening at port 1900 at all. When I check though, I have the minidlnad service conflicting with Roon:

root@nuc:~# ss -ulpn | grep 1900
UNCONN 0      0              0.0.0.0:1900       0.0.0.0:*    users:(("RoonAppliance",pid=272463,fd=639))
UNCONN 0      0              0.0.0.0:1900       0.0.0.0:*    users:(("RoonAppliance",pid=272463,fd=636))
UNCONN 0      0              0.0.0.0:1900       0.0.0.0:*    users:(("RoonAppliance",pid=272463,fd=635))
UNCONN 0      0      239.255.255.250:1900       0.0.0.0:*    users:(("RoonAppliance",pid=272463,fd=616))
UNCONN 0      0      239.255.255.250:1900       0.0.0.0:*    users:(("minidlnad",pid=1749,fd=6))

@Kevin_Mychal_Ong you are a more patient man than me!

Kevin_Mychal_Ong · April 5, 2022, 7:45am

That’s what you get when you work in IT You are so used to troubleshooting that you don’t give up easily.

Kevin_Mychal_Ong · April 6, 2022, 4:38pm

It happened again even after I uninstalled minidlna and made sure that there no UDP port 1900 conflicts anymore. Sigh.

AA_Parky · April 6, 2022, 4:53pm

@Kevin_Mychal_Ong could it be hardware related?

Maybe try a

lspci -v

Longshot but you may find a device without a driver.

Also maybe test the ram?

Well, yeah, I haven’t tested the RAM yet but based from the past occurrence of the issue, it’s clear that the symptom is when the roon-related services start taking up significant amount of RAM and as expected OOM killer will kill the service to stop this.

Up to this point, when I was restoring the database after the reinstall, I was using the Mar 27 backup. It could be that that in itself has the corruption. So I did another reinstall and restored the Mar 24 backup. Let’s see if that makes a difference.

Kevin_Mychal_Ong · April 10, 2022, 5:56am

Restoring to the Mar 24 backup did not make any difference.

I reinstalled again but this time I did not restore anything (so start from scratch) and after 2 days the issue is back. This is really getting out of hand. I filed a Roon support case since Thursday and haven’t gotten any replies yet!

Kevin_Mychal_Ong · April 10, 2022, 6:02am

@support @dylan @danny would you be able to help me here please?

danny · April 11, 2022, 1:01pm

Can you please send me your full logs from Roon?

The ones in /var/roon/RoonServer/Logs

Kevin_Mychal_Ong · April 11, 2022, 1:21pm

Certainly. The issue happened again just now and I had to reinstall (and removing the whole /var/roon along the process because it’s a required step) but I still have snapshots of my var folder from a few days ago. Here you go:

danny · April 11, 2022, 1:29pm

the logs you sent show no issues, no symptoms at all.

Kevin_Mychal_Ong · April 11, 2022, 1:45pm

When I was troubleshooting this while the issue is happening, I also don’t see anything in those logs which is why I stopped checking them. How do you propose we move forward? To summarize, when the issur starts:

The roon service is still started but with a state of “not responding” as shown in some of the logs snippets in my previous posts.
While the service is in this state, it will consume a lot of CPU and RAM resources until OOM killer kills the service.
Reinstalling roon without deleting /var/roon does not solve the issue.
Reinstalling roon after deleting /var/roon and starting fresh (no database restore) works temporarily until it starts happening again after around 1.5 days of uptime.

danny · April 11, 2022, 6:39pm

I need the newest logs from when the problem occurs. The logs you sent show me a functioning RoonServer.

Kevin_Mychal_Ong · April 11, 2022, 11:29pm

Ok. You posted a little bit too late since the issue happened 30 minutes before your first post here. Now that I applied the workaround (reinstall plus delete /var/roon and restore from backup), I will need to wait for approximately 1.5 days for the issue to happen again. I’ll wait and make sure it comes to a point where OOM killer kills the service and I will get you the updated Logs folder again. While I’m at it, do you need any other set of logs for when the issue happens again?

danny · April 12, 2022, 2:30am

/var/log/mesages or journalctl is good

Kevin_Mychal_Ong · April 12, 2022, 1:38pm

Ok. Right now, one endpoint is streaming off of the Core and it’s taking a lot of RAM. Is this normal?

Kevin_Mychal_Ong · April 12, 2022, 1:59pm

This might be related to this: Memory leak in Roon?! [See Staff Post] - #70 by Bill_Janssen

The person in the last post is saying his was using 48GB of RAM! That is insane.

Kevin_Mychal_Ong · April 12, 2022, 5:06pm

@danny

Here are my roon logs so far:

The service didn’t stop yet but the RAM usage is messed up. It got to a point that it was at 90% (of 32GB) usage even without any endpoint streaming. I see tons of Tidal errors in there but not sure if that’s what’s causing it.

Kevin_Mychal_Ong · April 12, 2022, 5:53pm

@danny ok, OOM killer just kicked in to kill roon. And as expected, the service won’t start anymore (not responding message). Here are the fresh set of logs:

/var/log/messages: Dropbox - messages - Simplify your life
journalctl -u roonserver.service -b: Dropbox - journalctl.txt - Simplify your life

These logs should show all events from the time I reported the high RAM usage a few hours ago up to the point where OOM killer kicked in. The physical RAM usage is very evident in the Roon logs and is mostly at 28GB or so.

noris · April 14, 2022, 3:52am

Hi @Kevin_Mychal_Ong ,

Your var-log is showing quite a few hard disk errors, perhaps this is attributing to the memory leak:

Apr 10 03:14:35 nuc kernel: [738485.103974] EXT4-fs (sda1): error count since last fsck: 138
Apr 10 03:14:35 nuc kernel: [738485.103982] EXT4-fs (sda1): initial error at time 1629819004: htree_dirblock_to_tree:1003: inode 70516840
Apr 10 03:14:35 nuc kernel: [738485.103988] EXT4-fs (sda1): last error at time 1647358208: ext4_empty_dir:3005: inode 95815045

You may want to run a disk check, reinstall the OS and/or use a different hard drive.
