RAM memory problem

I found that after using comfyui for a period of time ( like a week ), the program's RAM memory will continue to accumulate until it becomes too high, and finally the process will terminate.

Excuse me, is there a way to automatically release RAM memory when it reaches a certain level, or is there a way to prevent memory from accumulating continuously?

I have used “--normalvram” command and I know “--disable-smart-memory”
My GPU is 3080，VRAM is 10GB
MY RAM is 20GB

Is there any way to solve the problem？

Thanks！
