smoal 0 Posted September 19, 2018 Share Posted September 19, 2018 (edited) Hi, I am a new user of the emby server on a synology DS214 Play. When scanning the library or viewing a film, the synology become unusable, it is totally overload. The resource monitoring shows that the disk are over 90% used, the CPU shows an Atte E/S over 50%. The problem is that other software on synology do not work anymore... even using telnet is difficult ! you will find the rundiag log in attachment.

smoal 0 Posted September 20, 2018 Author Share Posted September 20, 2018 Hi, I finally catch the problem, it was due to 3 iso file in the library, If I remove these files and restart emby, all goes fine. Here are snapshots describing the problem : Add the iso files again (and remove them), I forced the library scan to stop, but it has no effect on the CPU load So the problem is solved one my side. If you want me to make more test, tell me ! Link to comment Share on other sites More sharing options...
smoal 0 Posted September 20, 2018 Author Share Posted September 20, 2018 Hi again, I spoke too quickly, I wanted to see a film (mkv), it blocks when loading the mdb info, then my NAS was overloaded again (same as previous description)... I have to restart my nas : it was impossible to access to the emby server webpage or NAS packages status... and I didn't find the shell command to stop the server.

So i cannot stop the package this way. I use the package embyserver stop command, then the status to check that the embyserver has stopped.

solabc16 379 Posted September 25, 2018 Share Posted September 25, 2018 (edited) Hello @@smoal Look through the logs you uploaded, I don't see anything fundamentally wrong. How large is your library and has it successfully completed a full library scan? I can see that FFprobe was running across all titles in your library, this would have kept CPU and IO high for an extended period (as shown in your graph). Your system is capable of handling a remux, as we can see in ffmpeg-remux-983eddb1-041c-4bb5-be7d-7c60986f18fd.txt, which achieved around 45fps on average. However, the transcode is out of reach, with the fps averaging less than one, you'll need to look at alternate options - preferably direct play. Stream mapping: Stream #0:0 (h264) -> overlay:main (graph 0) Stream #0:3 (dvdsub) -> scale (graph 0) scale (graph 0) -> Stream #0:0 (libx264) Stream #0:1 -> #0:1 (dts (dca) -> mp3 (libmp3lame)) There is one historical crash from the realtime monitor, but it's not happening frequently so I wouldn't suggest any further action at this point. The library scan on it's first run will be intensive, and it'll need to be left to 'do its thing' - if this has run fully, then we'll need to understand why FFprobe is running through all of the titles in your library.

smoal 0 Posted October 3, 2018 Author Share Posted October 3, 2018 Hello, I have made some tests this morning, I reduce my film library to 3 films. The library scan finished in a few seconds in the emby server page dashboard. But I still cannot play film and I had the same problem of overload (High Atte E/S) Just the time to write this response, I saw that the Atte E/S in the resource monitor goes done suddenly, and then I can play the film without any problem. When I add a film to the library and make a rescan, I have the same effect, I must wait 2 or 3 minutes before being able to play the film. So it seems that the scan is not finished in some way, or something is still running after the scan is finished in the dashboard. Perhaps the FFprobe process. For information, my library is very huge, with film of 10/20 GBytes Is the scan information in the dashboard is sufficient to say that the scan is totally finished ? I saw a topic about HW transcoding for synology DS214play, i will take a look. Regards, @smoal Link to comment Share on other sites More sharing options...

smoal 0 Posted October 6, 2018 Author Share Posted October 6, 2018 The problem is that it takes 100% of the CPU when it transcode and in the meanwhile, the synology became unusable... it may takes days to transcode. With the new version, I can access to the transcode menu and indicate the "error", with the older version, it was simply not possible since the NAS wasn't replying. If you don't want to support me, please tell me. It seems like I'm bothering you. I just want to use the Emby server on my nas because it seems to be a good alternative to other solutions...

Luke 37137 Posted October 6, 2018 Share Posted October 6, 2018 If your NAS can't handle the subtitles then why turn them on? Why not add external .srt subtitles? These are always more efficient. Link to comment Share on other sites More sharing options...

My NAS is totally blocked and cannot even logon, with no possiblity to investigate the problem. It seems you don't understand the point Luke : when I say the NAS is overload, It means I don't have even the possibility to go to the dashboard... even ssh doens't work correctly, the NAS is a blackbox...
