Memory usage on Synology NAS

[David_Jehring]

I have had to restart the Roon service on my Synology DS920+ NAS several times. I get performance issues from Roon (slow to connect, skips tracks) and when I look the NAS is using over 90% of RAM. Restarting the service will clear the problem for a few days. I have increased my RAM from 4gb to 8gb but this simply delays the inevitable. This would appear to point to a memory leak in the Roon Service.
I am using the latest version of the service (2021-03-08) on DSM 6.2.4-25556

Can confirm this with a 1517+. 16GB of RAM so my grace period is even bigger. But the pattern is the same: the longer Roon is running the more RAM gets drained.

It’s strange, I’m not seeing this issue with my RS3617xs. 12% RAM usage (32GB installed). Roon has been running 24/7 since the last update.

Memory leak in Roon?! [Solved: Update to Build 970]

@support I am using Roon with great pleasure for more the two years now. Many thanks for that! The latest 1.8 update is a improvement for me because of the better classical search functions. Still, I have a problem. Since I use Roon, it is constantly ‘eating’ my system memory. Over the course of days and weeks, Roon’s memory usage continues to increase: from 1 Gb in the beginning to 3 Gb and more. Eventually I have to restart Roon. This is a little annoying. I am not the only one complaining …

Same thing on my DS718+ upgraded to 8Gb of RAM.
Roon server easily goes over 4Gb in a matter of days.
Is this normal?

I’ve found a satisfactory workaround for the issue with two scheduled tasks in DSM to stop and then start the Roon service at 03:00 every night. This has the secondary benefit of stopping any radio streaming I may have forgotten to stop before bed, which saves KPIG a few cents. I run Roon happily on a DS718+ upgraded to 8Gb of memory, 30K local tracks in the library.

I came here to post about the same problem and found this thread. Roon core on Synology “eats” memory over time. I have to restart Roon from time to time. It looks like there is a development of a new package for DSM7. Maybe it will be better…

I’m looking for a more up to date thread on this issue.

Just upgraded from 4 to 32GB (along with a 1TB SSD read cache), and all that lovely new RAM is slowly being gobbled up. I havn’t yet experienced the improvements to the laggy browsing I was hoping for .. sigh ..

Using an older I7 NUC running Rock, so that’s next in line for upgrade ..

[G_P]

You have only 1.2GB used out of 32GB. Cached is not a used memory. Synology caches some files from hard drives into available memory but it will give up that memory if needed for processes. You can use Task Manager in Resource Monitor to see how much memory is used by processes. You have no problem.

[Mr.Flibble]

I’m a little confused.

Are you running Roon on your NAS or Rock on your Nuc?

The RAM chart must be from your NAS as you don’t get that with Roon Rock.

[Matthew_Talbot]

Sorry. Running Rock on Intel NUC7 i7 BNH with 8GB RAM

Currently I’m looking for any performance improvement with the NAS upgrade.

It’s so difficult (for the average person?) to understand how the different variables affect overall performance just be reading the forums. Biting the bullet and testing myself .. too many years of painful experience.

Next experiment is sidelining the NAS for storage entirely and migrating the source to a dedicated OWC Express 4M2 with 4x4TB SSDs.

After that I’ll sideline the old NUC and hook up the new SSD library to a Mac Mini M2 with 8GB RAM (low I know).

Finally(?) I may be looking into a newer NUC or M4 with max RAM.

Oh yeh .. checking the EdgeRouter networking performance before spending more $.
