GPU memory leak?

[HDCL]

This has become a problem for me as well causing a crash if I don’t manually restart SpaceDesk every so often. The used virtual memory will hit a limit at some point and Windows will crash. This usually takes 2 – 4 weeks of up time and 32 or 64 TB of GPU virtual memory allocated at which point Windows 11 runs out of resources and the system crashes with a Blue Screen of Death. I have created a manual task that kills the SpaceDesk process and restarts it at every resume from sleep and that has elliminated the issue, but it is still annoying. The Virtual Memory counter in Windows keeps creeping up indefinitely until the system crashes. Before a system crash, other applications like games start to run into issues with insufficient GPU memory error and just the game will crash. This is the only application that exhibits this behavior of 10K – 50K of virtual memory increase every second.

Hi @hdcl,

For further analysis, please send us the diagnostic info of your primary machine.
Just open the spacedesk Driver Console -> Diagnostics, click the “Save All Information” button.
If message box appear, please click “Yes” and it will restart as Administrator, then click again the “Save All Information” button.

PS: Saving all information will take a few seconds, then please send us the whole folder which contains all the diagnostic logs collected.
Please right-click the folder -> Send to -> Compressed (zipped) folder, then attach the *.zip file in your next reply.

By the way, we moved your post into a separate topic to avoid confusion.

I have the diagnostic information. This is after a fresh restart of spacedesk.

I am getting a “allowable file size exceeded” error. The zip file is only 524 KB. I broke it into 2 parts

Hi @hdcl,
Thank you very much for sending the diagnostic files.

Can you uplease try/check the following:
– Update your NVIDIA GeForce RTX 3080 graphics adapter to latest version. You can update via Nvidia GeForce Experience or download directly from their website https://www.nvidia.com/Download/index.aspx?lang=en-us.
– Check in your C:\Windows\minidump folder if there’s any recent *.dmp file for the Windows crash (BSOD).
If it’s there, please also send it to us.
– Check the memory usage of spacedeskService.exe in task manager.
– Maybe also send us the screenshot showing the high GPU virtual memory usage when spacedesk is active.

NVidia driver has been updated. There are no minimump files (I think I have full memory dump enabled and I did not let it finish dumping 32GB.)

Attached are a series of screenshots about 1 – 3 minutes apart showing the increasing Dedicated GPU Memory usage in task manager
