arc a380/a750 qsv enc sys paged memory leak

[focus]

hw: i7-12700 + arc a380/arc a750

os: win10 21h2

sys memory: 16GB ddr4

igpu: hd graphic 770, driver ver 31.0.101.3490 ~ 31.0.101.4146

dgpu: arc a380/a750, driver ver 31.0.101.3490 ~ 31.0.101.4146

bios: rebar enable

software: intel\oneapi\vpl\2023.0.0\bin\sample_encode.exe  and  ffmpeg.exe

Use hd graphic 770 to encode 4kp50 h264/h265, nv12/p010/y210 yuv format, mfx.LowPower = MFX_CODINGOPTION_OFF, no sys paged memory leak, both sample_encode.exe and ffmpeg.exe.

Use arc a380/a750 to encoder 4kp50 h264/h265, nv12/p010/y210 yuv format, mfx.LowPower = MFX_CODINGOPTION_OFF, sys paged memory leak about 7MByte every minute, both sample_encode.exe and ffmpeg.exe. Close the encoder application cannot free sys paged memory.

Meanwhile, both sys physical memory and virtual memory will be exhausted, if i use a tool to clean memory, sys physical memory will be free but virtual memory not.

So I use a very large hard disk, to set huge virtual memory, about 2T, and use tool to clean memory every day, video encoder application can continuous work over hundred days. But when close the video encoder application and open it again, it cannot run unless reboot the machine.
