OVRServer_x64 Memory Leak/Not clearing working set

Will be sending this directly to support as well.

Here's the issue:

This service is currently taking 4gb of memory. Without anything attached. The Oculus program is not running. Firefox has a youtube video playing. I checked via other apps; this is working memory, not non-paged or standby memory. So ovrserver_x64 is using 4gb of memory without any use or reason to. 

But that's not all. In the hour or so while I was investigating this,

It took another 800mb or so of memory. In processhacker it's actually taking about 5.1gb total private memory (ie; reserved memory, and most of it is working memory)

This is absurd. I can imagine this could be the cause of many people's issues if they have less capable memory or a lot less of it. If I only had 8gb, I'd be well over my limit and into the pagefile, ie I would probably bsod or the program would crash. I think this would be fine (jk, this is still ridiculous for a simpler server app that isn't even running) if I had Link going or something. But, like, really?

I've created a .dmp of the memory but it's obviously 5gb in size so I'll have to look at it privately I guess. If anyone else can notice this issue especially when NO SOFTWARE is active, that would be interesting to hear.

    I got the same problem since yesterday. It happens when I unplug my vr. In my case I got 32 gb of memory but it fill all of them.

    The same thing is happening to me now; I've only caught it going up to around 1.5 GB, but that's still more than it should be taking up while not in use...

     

    Did you get any kind of response from Support? Are there any known workarounds besides rebooting?

    same problem, in the background this process eats from 80 mb to 6 gb and more memory, until my computer crashes 😤

    4 years later and this is still an issue...

    This literally just killed my PC. I did manage to restore it but I had to restart it cuz it disconnected my other monitors...

    64 GB of RAM and it just sucked up all that was available and stopped my Browser and everything else from working... I played like 5 minutes of VR, exited VR from SteamVR as usual and turned off my Headset. After like half an hour of me sitting at my office desk I just saw that 2 of my 3 monitors were turned off and my browser had a white screen "Low memory" and I saw this...

    Recently started having this issue. I'd be in VR only for it to suddenly freeze up, and I would see that my 32GB of RAM has been filled up. Closing the Link program clears it, but it's not an actual fix.

    I dont think its an isue of ram, as i have a r9 5900x, 64gb of ddr4 ram, rx 7800 xt and have the exact same isue. It seams to be more on AMD cpu AND gpu systems. Something somewhere broke and its not clearing cache correctly.

    Same Issue, 7800X3D 7900XTX 64GB Ram, process lasso crashes my VR anyways after 3 HRS, 23 and 24H2 does not matter, reinstalling windows does not matter, Updating bios, GPU Drivers even on headset level, quest 2 and 3 does not matter

    Same problem happens while playing randomly with Quest pro (latest firmware) on steamvr (vrchat), ovrserver ram usage will eventually reach 100% and cause other processes to crash/freeze
    My specs are:
    asus mother board
    rx 7900 xt 20Gb memory, driver 25.3.1

    ryzen 5 7600X

    32Gb RAM

    tried most things like reinstalling the oculus app, disabling smart access memory, cleaning caches, updating everything

    I should add this issue only started happening after updating both the quest pro firmware and the oculus app to the latest version
