High RAM usage on QNAP TVS-873

Server Version#: 1.16.6.1559
Player Version#: NA

I have 20GB of RAM installed in my QNAP, but keep getting a high RAM usage warning.
For the past month it as occured, I even did a reinstall on my NAS, wiping out all my settings.
Reinstalled Plex.
But within 24 hours I notice it seems to be back to using over 6GB of RAM even when at idle.
I am now at the point of either putting more RAM in the system or moving over to Emby.
Can anyone shed some light onto why my plex could be using so much RAM even at idle.
I can provide plex logs if needed.

Thank You.

I’ve no experience with your model, but my TS-451+ never used more than 3 GB of RAM, even though I have 16 GB installed. I am running QTS 4.3.6 atm. I’ve tested the exact PMS you’re reporting.

When you open up QBoost, which apps are using all the RAM?

Currently under Qboost its showing:

Plex Media Server 5.48 GB

Tautulli 88.14 MB

Microsoft Networking 53.07 MB

Web Server 19.87 MB

NFS Service 13.06 MB

Apple Networking 7.79 MB

SSD Profiling Tool 0 Byte(s)

Overall System Ram Usage is sitting at 86%, not sure how with 20GB of RAM installed but even so, I am sure plex shouldn’t be using that amount of RAM.

Thank you for your reply

I read that and said “Oh heavens”
My Plex server only uses 175 MB on my QNAP.

Let’s see if we can narrow it down a bit more. Open up the QNAP Resources Monitor, look in the Processes window, and click the down arrow next to Plex Media Server so that you see the breakdown of child processes under PMS and their RAM usage. What’s the offender?

Assuming it’s user error like it mostly is with me xD, how hard would it be to wipe your Plex install and restore only the media, using brand new folders so that it starts again from scratch? I don’t even know what that would do, but I feel like a default install would never run like yours, you know what I mean?

Good luck!

Out of curiosity, do you have Live TV / DVR enabled using XMLTV for guide data?

Looked at what is being used

Plex DLNA Serve - 4.7 GB
Plex Media Serv - 539.4 MB
Plex Script Hos - 71.9 MB
Plex Media Scan - 38.9 MB
Plex Tuner Serv - 2.3 MB
EasyAudioEncode - 1.7 MB

So it seems it the Plex DLNA Serve thats causing the problem of RAM being used up.

Nope dont have TV / DVR enabled.

Oh I see, yeah, DLNA is eating it up. Well I’m a noob when it comes to that, but isn’t DLNA mostly for making the API available to other apps? If you don’t need that, maybe you want to disable it in Plex settings?

If you’re DLNA is on but idle and the RAM use grows steadily, it’s acting like a memory leak. Does this problem occur in 1.16.5?

I had Plex DLNA turned off and also QNAP DLNA disabled on QTS 4.3.6, and PMS-1.16.6.1592.
I just turned Plex DLNA on. It only uses 21 MB of RAM. Why me? :slight_smile:

You might want to disable and enable Plex DLNA and post the PMS logs to see if there’s something amiss when it gets enabled. Hopefully an employee will chime in then.

Good luck!

The issue didn’t accrue straight away with DLNA on, it happens over a 24 hour period.
SO no you wouldn’t of noticed it when you first turned it on.
I actually dont use DLNA, so yeah it was sat on idle. Its happened for a long time, even on 1.16.5.
I have now left Plex DLNA disabled, it as solved the RAM eating problem.
Sounds like they do have a issue with a memory leak with that service.

I will re-enable it later tonight and post logs of what I see, even tho it happens over a long time (24 hour) period.

Thanks it was some messages during DLNA startup that I was hoping to compare to my logs.

Let’s say 5 min after restarting PMS with DLNA capture the logs.

Mine RAM usage has grown to 22 MiB overnight, argh.
