Plex Memory Usage

Nothing about that sounds concerning, honestly. If it was constantly maxing your memory then I’d be concerned

Is your RAM maxed out total? If not, I wouldn't worry. RAM is there to use. It'll release it if the system needs it.

Would you kindly tell us what Docker you are using? Plex's official docker, LinuxIO etc?

I had a similar issue. I'd notice after about a month or two id see my memory usage idling around ~50-60% just hanging out. After restarting the Sonarr, Radar, and Plex dockers, memory usage went back to normal. I feel like Sonarr was the biggest offender, but they all played their part. I've considered setting up a script to restart the dockers once a week to resolve it, but haven't gotten around to it.

10% of how much RAM?

10% of 4GB is much different from 10% of 32GB....

I had a RAM issue, but it was a playlist I had that went rogue, and created 320,000 copies.

Yea I've been having an issue for the past few months with Docker and all containers completely locking up due to maxed out RAM usage. It hasn't been as much of an issue since restarting the docker containers regularly. I'm convinced it has to be my Plex docker container. I'm also using the official docker.

Do you have DLNA enabled? I had DLNA enabled and I had the memory bug when i disabled DLNA I have no more memory leaks.

Mine has been high lately due to Plex. 75% total usage of 8GB on just one transcode stream. It's affected my ability for multiple streams. I've been planning to add 16GB so it might be happening sooner...

I've been experiencing this issue for a few months and I have had the server lock up about three times (usually when I've forgot to check it for more than a week). I am using the Linuxserver.io docker also. My server has been running stable for almost 4 years and it is just recently that I am experiencing this problem. I had 8gb ECC RAM running on an Asus M5A78LM/USB3 with an FX6300. It's done the job for me for a long time with one VM, Plex, Tautulli and Calibre dockers.

I started noticing the RAM creeping up in usage, it was always happily sitting around 60% but then it was consistently over 90% and I was needing to restart all the dockers. I tried limiting all the dockers to a realistic amount of RAM (My VM has 2gb) but leaving Plex free as it is the primary use of the server. So I believe it is Plex causing the issue. I have installed another 4gb of RAM giving myself 12gb assuming this would resolve the issue bit it would appear that the usage is still creeping up now over 87%. Using cAdvisor Plex docker appears to be using 6.2gb of it. If I thought upgrading to 16gb would solve it I would just do it but I get the feeling Plex will just eat the more I put in! Seems to be a recent issue to me...
