Exceeded max size of memory

[Starcrackeriii]

I run sdnext in docker container and it works well when generating small size images, but with size 1024x1024 there is the problem:

RuntimeError: Exception from src/inference/src/cpp/core.cpp:104:
Exception from src/inference/src/dev/plugin.cpp:53:
Check '!exceed_allocatable_mem_size' failed at src/plugins/intel_gpu/src/runtime/ocl/ocl_engine.cpp:142:
[GPU] Exceeded max size of memory object allocation: requested 8589934592 bytes, but max alloc size supported by device is 4294959104 bytes.Please try to reduce batch size or use lower precision.

I use intel uhd 770 as gpu with 32g ram , but the exception says my device has only 4g ram,but i allocate 8g for this container ,docker commands are as follows:

docker run -it -d \
--name=sd-webui \
--device=/dev/dri \
-m 8144m \
--cpuset-cpus="0,1,2,3,4" \
-p 7860:7860 \
-v /volume7/docker/AI_TOOLS/stable_diffusion/models:/sd.next-webui/models \
mycontainer/sd-webui:2025.2.10 

Dockerfile:

Really hope anyone could help me
