Description of Issue

Very high RAM usage on the Synology (> 8 GB). More than half of RAM is used up by the .NET Roon process.

Repro steps are:

• Restart Roon Core
• Start using it a bit (primarily through the MacBook Roon client while at home, and Android Roon Arc client when not at home)
• (This will trigger the situation as described in Roon ARC Causing RoonServer/Remote Performance Issues [Investigating] - #81 by jeroendee sooner or later)
• Check in the Synology Resource Manager and observe the very high RAM usage.

[DDPS]

This is not abnormal. Roon takes advantage of as much available RAM that is not otherwise in use as it can. So long as you are not having any functionality issues, you should be a-ok. Please let the community know if this isn’t the case.
