Akropolis 0 Posted October 7, 2015 Share Posted October 7, 2015 Since some time now I have problems playing video's with emby. Looks like emby uses all the memory it can get fast. I have a dedicated system for emby with 2G of RAM. Emby uses it all: emby 25879 4.6 80.3 3958040 1514316 ? Ssl 15:44 1:25 /usr/bin/mono-sgen --optimize=all /usr/lib/emby-server/.... 80% memory use. My current version (previous versions have the same issue): emby-server-3.0.5724.6-349.1.noarch Trying to play a video gives me: 2015-10-07 16:04:31.4726 Error - HttpServer: Error processing request for /videos/e6fc7608c572c30e7d175228a4b8acdc/stream.webm?DeviceId=842099d6030a4fdf951623fef13504888012f78c&MediaSourceId=e6fc7608c572c30e7d175228a4b8acdc&VideoCodec=vpx&AudioCodec=vorbis&AudioStreamIndex=1&VideoBitrate=872000&AudioBitrate=128000&MaxHeight=480&StartTimeTicks=13785161790&ClientTime=635798234702620610&PlaySessionId=<sessionid>&api_key=<apikey>&EnableAutoStreamCopy=false *** Error Report *** Version: 3.0.5724.6 Command line: /usr/lib/emby-server/bin/MediaBrowser.Server.Mono.exe -programdata /var/lib/emby-server -ffmpeg /bin/ffmpeg -ffprobe /bin/ffprobe -restartpath /usr/lib/emby-server/restart.sh Operating system: Unix 3.10.0.229 Processor count: 6 64-Bit OS: True 64-Bit Process: True Program data path: /var/lib/emby-server Mono: 4.0.3 (Stable 4.0.3.20/d6946b4 Thu Aug 13 12:39:47 UTC 2015) Application Path: /usr/lib/emby-server/bin/MediaBrowser.Server.Mono.exe ApplicationName='/bin/ffmpeg', CommandLine='-ss 00:22:58.516 -fflags +genpts -i file:"/media/tv/myvideo.mkv" -map 0:0 -map 0:1 -map -0:s -codec:v:0 libvpx -force_key_frames expr:gte(t,n_forced*5) -vf "scale=min(iw\,720):trunc(ow/dar/2)*2" -pix_fmt yuv420p -speed 16 -quality good -profile:v 0 -slices 8 -crf 10 -qmin 0 -qmax 50 -maxrate:v 872000 -bufsize:v (872000*2) -b:v 872000 -vsync vfr -map_metadata -1 -threads 5 -codec:a:0 libvorbis -ab 128000 -af "aresample=async=1" -y "/var/lib/emby-server/transcoding-temp/18f540c67c22cd04ef27d38b9ff85227.webm"', CurrentDirectory='', Native error= Out of memory ServiceStack.HttpError No Stack Trace Available After I do a emby-server restart it works for a while.

Solution fc7 123 Posted October 7, 2015 Solution Share Posted October 7, 2015 (edited) Which distribution are you using? You may want to low down the nursery size for mono. If you are running on CentOS or Fedora, you should be able to do this by editing /etc/emby-server.conf and giving it a lower size (64MB) instead of 512MB which is the default. For example adding the following line: MONO_ENV="MONO_THREADS_PER_CPU=500 MONO_GC_PARAMS=nursery-size=64m" Please note that this will cause mono GC to run more frequently and it may have a negative impact on Emby performance.

Thanks for your reply! I am running CentOS 7.1. But what does nursery-size mean? I take it that 512M is the default, so by default 2GB of memory is not enough?

fc7 123 Posted October 7, 2015 Share Posted October 7, 2015 Don't get my wrong but I don't think we should discuss about mono memory handling here, since it's an Emby forum. For more information on mono's nursery size and what it is you will find plenty of information in google. Since you are running on CentOS 7 just try what I suggested before. Add the configuration value to /etc/emby-server.conf and restart emby-server service. About system memory size, it really depends on how much you load it. I'm also running Emby on a dedicated VM with 2GB of RAM and I'm not having this problem but I must admit that my server only has 2 or 3 users and usually not even concurrent so the load is not really relevant. Others may have a dozen concurrent users with some of them doing transcoding at the same time so memory and CPU requirements will be much different. Having said that if we detect that the default value is oversized, andcausing issues to many users we will review it and reduce it until we find a correct balance.

Akropolis 0 Posted October 7, 2015 Author Share Posted October 7, 2015 Sure, I get it. Found some info here: https://developer.xamarin.com/guides/android/advanced_topics/garbage_collection/ I am the only user on the system. Does the amount of content make a difference? I will try your solution, thanks! Link to comment Share on other sites More sharing options...
Bernie V 7 Posted December 29, 2015 Share Posted December 29, 2015 I'm having also a lot of out of memory issues with a Raspberry Pi2 (with osmc, debian jessie). Can I try this solution also? Link to comment Share on other sites More sharing options...
