DefaultCPUAllocator: not enough memory

Hi,
i got this error on my comfyUI when trying to generate images,
is there any way to solve this? sorry i am not that great with codes,
it does not happen all the times, it happens 5 out of 10 pictures that i tried to generate.
(tested with 100 queue)

Error occurred when executing VAEDecode:

[enforce fail at ..\c10\core\impl\alloc_cpu.cpp:72] data. DefaultCPUAllocator: not enough memory: you tried to allocate 2359296 bytes.

my spec: rtx 3060,i3-12100f,16gbs ram(8x2),
