    Two different windows machines. 

    API calls      : 
         Windows 10 Pro Build 19045
         Processor Intel® Core™ i5-7300HQ CPU @ 2.50GHz, 2501 Mhz, 4 Core(s), 4 Logical Processor(s)
         Installed Physical Memory (RAM) 16.0 GB

    Core Server : 
        Windows 11 Pro Build 26100  
        Processor AMD Ryzen AI 9 HX 370 w/ Radeon 890M, 2000 Mhz, 12 Core(s), 24 Logical Processor(s) 
        Installed Physical Memory (RAM) 32.0 GB
        This is a clean install.  Nothing else on server.

    Six hours after reboot : 16g RAM usage for Jellyfin.Server

    The Windows 10 ran an alternative Media server for years.  I purchased this new machine after having the ram issues.

    Unless I am understanding the code wrong.  This Ram issue would be expected with large libraries.

    I was looking at issues on GitHub and I also think this is related to this issue :  [Issue]: Library scan causes excessive RAM usage · Issue #11588 · jellyfin/jellyfin
    This sounds like the same thing I am seeing.  if you interact with the library..  The more you interact the more the memory grows and never shrinks.  scanning is a good example.
