Resource leak

[Eelke]

I have an Intel ARC 380 card on a system with a AMD 7950X CPU and 32 GB of RAM.

When the system is not rebooted for a few days the system get's low on memory. With task manager it is not clear where the memory goes. With rammap64 tool the first sign of something wrong was that the Page Table grew to many gigabytes while it should be a few hundred megabytes. Also on the process tab of rammap64 I noticed lots of processes  that were not listed by task manager.  What I understand is that these are procesesses that are terminated but windows cannot fully clean them up because a driver or other app is holding a handle to the process.

At the end of december I did a clean install of windows 11 which did not solve the problem. Then last week I connected my monitors to the build in graphics and removed the arc drivers and now memory usage stays normal after several days.

The driver i was using last had download filename gfx_win_101.6332_101.6253 but i have had the same issue with several older versions.

AMD Ryzen 9 7950X

When you removed the Arc drivers and switched to the integrated graphics, the memory usage remained normal, indicating the issue is likely related to the Arc GPU drivers or how they interact with the system. Possible Causes would be Memory Leaks in the Driver, Driver Incompatibility or Bug, Handle Leaks or Driver Holding Handles, I recommend to update your Intel Arc GPU drivers to latest using this link: Intel Arc A380 Sometimes, specific hardware and software combinations can cause unexpected behavior, and Intel have released patches to address these issues. Perform a clean boot of Windows (disable non-essential startup programs and services) to ensure no other software is interacting with the GPU drivers in a way that could contribute to the issue. This can help isolate whether the issue is solely with the Intel driver or if another application is involved.

well, issue seems related to how the Intel Arc 380 driver handles memory allocation, particularly when it comes to cleaning up resources after terminating processes. By updating drivers, checking for known issues, and isolating the problem, you can better pinpoint whether it’s a bug in the driver, a hardware conflict, or a system configuration issue.
