The RAM of my QNAP NAS fills up

Ralf_Weisskirchen · October 27, 2019, 5:09pm

QNAP Server: TS 473, 4 GB RAM
Roon Core: SSD 120 GB
Music: dual 1TB mirrored drives
Network: Fritzbox 7590
Audio device: Meridian 218

I notice that the RAM “fills up” to 99% within a few weeks. When I shut down the server and start again, the RAM is 35%. Why is the RAM filling up?
What can i do?

Your QNAP uses a Linux kernel and it is common for Linux to allocate all the memory, particularly for disk caching. This is not a problem; when an application needs more memory it will be reallocated.

thank you for the information. I am reassured

Please note that Roon Server would benefit from 8GB RAM, so you may want to consider upgrading your memory.

The difference in performance on the QNAP running the Roon Core from 4GB to 8GB is very noticeable.
