Emby is blocking NAS and crashes in a daily interval

[jaunusa 1]

Hi,

 

my DS716+ ist crashing once per day since about one month. First thing that happens is that the memory usage rises up to about 90%. After that Synologys Webinterface becomes very slow until it doesn't respond. Before that the Resource Monitor shows that Emby is using a lot of memory.

After a crash I had a look at the logs, the file is huge and full of errors (mainly error: "Too many open files). I supmitted the logs and hope they are helpful.

 

Logs: sendlogs_nas_synology_braswell_716+_20171214T152617UTC.tgz 

 

Does anybody else has this issue?

@@jaunusa, can you attach the emby server log here as well? you can learn how to do that here:

Thanks !

Is the nas a separate system, or are you running emby on the nas? If the former - how are the files shared i.e. smb, nfs, ftp etc...

 

I've seen the "too many open files" issue , when the media is on the same device as the media and that's largely because emby is doing something wacky that's allowing it to exceed the file descriptor wall limit defined by most sane kernel configs. Haven't seen this remotely though, but I guess if you were using nfs it could still happen.

[jaunusa 1]

Yes, emby is running on the same NAS device where the media is. Strange things happening there, the log file is 250MB large. I uploaded it to google drive and will send you a PM with a link, @@Luke.

 

sorry for the late response

There are lots of these in your log that are causing disruption with the embedded web server:

Exception.Message: Connection reset by peer

I will need to search and refresh my memory but when we've seen that in the past it's always been due to some nuance of the network configuration.

[jaunusa 1]

@@Luke, which network configuration do you mean, hardware setup?

 

It could be possible that this daily crashing started after I connected the NAS with a router that is setup as a wireless client bridge. Before that emby crashed fewer. 

[Luke 40131]

That is possible, yes.

[jaunusa 1]

I connected the NAS directly to the main router, without the wireless bridge inbetween. But I'm still facing daily crashes. Any idea what I could try to fix the problem?

@@Luke, don't you think it is the same problem as before, when the NAS was connected through the wireless bridge? I already sent you that Log.
At the moment I am away from home and the NAS is restarting every morning to prevent from beeing blocked by emby. If you need another Log, I will let it block once again.

Hi, have you tried the 3.2.60 update? thanks.

[jaunusa 1]

@@Luke, I'm back in the local network for a few days. So I could test version 3.2.70 and exatly the same happens as before. Could it be possible that the chromecast issue "network stangling" is causing this problem?

[Luke 40131]

I wouldn't think so. Can you please provide a new log with the latest version. Thanks !

[jaunusa 1]

@@Luke, sent you a PM with logs

Edit: I have to mention, I killed Emby manually through DSM, because I could see the RAM rising dramatically.

[Luke 40131]

Can you try removing all plugins again and see if the issue persists? thanks !

[jaunusa 1]

I removed all plugins and restarted Emby. The NAS won't restart automatically, so we will see if it happens again.
There was a strange plugin listed: "Iso Mounter". I can't remember I installed it.

[jaunusa 1]

Emby crashed again yesterday, same behavior as before with all plugins installed. The log file is about 400MB large, do you need it @@Luke?

[Luke 40131]

Yes that would be great, thanks.

[jaunusa 1]

I'm still having this issue, but I suppose I got the thing the causes the problem. Hopefully somebody can confirm this problem.

 

After long thinking about all components in my home network that could cause the problem, I remembered the kodi with installed emby addon is mostly running in the background on my Android TV. Because Emby wasn't blocking my NAS and crashing every day, it was possible that the emby addon had some issues, still running in the background on the TV. So I always shut down emby after using it and the problem disappeared. Emby is no more crashing every day.

 

Is that a known problem, any ideas to fix it?

[Luke 40131]

Can you send me a new log with the latest server release? Thanks.

[jaunusa 1]

I sent you a PM with a download link for the log. Have you seen it?

[Luke 40131]

Have you tried the 3.4.1 update?

[jaunusa 1]

Yes, still the same problem.
