Wfuzz eating all ram and freezing Kali

Hello, whenever I try to use Wfuzz in kali (I use rockyou.txt as lists, but I've tried with smaller files, same issue) after a few minutes the laptop freezes. I have 8gb of ram, I can see from task manager that the memory usage rises steadily every second until it reaches full capacity.
I'm a bit of a newbie but I've tried flushing the cache, lowering the number of requests in wfuzz but nothing sam results
Why is it doing that and what can I do about it?

Thank you!
