Xpenology RAM Usage

[n00b42 33]

My Xpenology Setup became quite slow, therefore I looked into the process list and discovered that it used around nearly all available RAM (around 12 GB)

 PID*   VSZ    VSZRW   RSS   (SHR) DIRTY (SHR) STACK  COMMAND
 25832  25.8g  22.7g   11.9g 0     11.9g  0    264    /var/packages/EmbyServer/target/mono/bin/mono /var/packages/EmbyServer/target/server/MediaBrowser.Server.Mon

In Emby Administration "Running tasks" showed a "Scan media library 97.7%" which seems stuck as it did not change within half an hour.

 

Not sure if related but the logs are filled with errors like

Hi, this will be resolved for the next release of Emby Server, except for the file saving errors, as that is something you'll need to handle. It would appear you've enabled saving metadata into media folders, but Emby Server does not have write access to that location. You'll want to review the access privileges for the Emby service account. Thanks.

1) The RAM usage went back to around 300MB after I stopped and restarted the service, not sure if or when it will increase again.

 

2) Actually, the saving works as Emby already downloads all the metadata and media in the movie directories. Meaning, i did not encounter problems with saving the metadata myself, only saw lots of those errors in the logs.

Maybe some race condition / locking issue of XPenology, will look if I can find more information....

Thanks for the info.
