Describe the bug
it started a few days ago, npm is consuming 80-90% of my cpu in 2 process, heres a pic of my htop

https://drive.google.com/file/d/12-ZBtBSNjaHAeP_KC6kEVSnZtHchsYlo/view?usp=sharing

its driving me cracy, i cant make it to be normal again, never seen this b4, logs r useless, theres nothing there, its all like its acting normal

sometimes the name of the command change to nginx worker process is shutting down, but the process id remains the same, if i shutdown npm, my server goes back to normal but that doesnt work all the time, i have it on ubuntu server as a docker with other 12 docker containers, its been runing fine, but the issue started all of a sudden 3 days ago

If i do docker compose -f npm/npm.yml down && docker compose -f npm/npm.yml up -d to restart the container, everything goes back to normal but like i said it doesnt always work, until it starts all over again, sometimes it takes a bit, sometimes it takes longer, but eventually it starts to take 80-90% of my cpu again.

Nginx Proxy Manager Version
v2.12.3

To Reproduce
As soon as i start the container, my cpu goes to 80-90% usage by NPM

Expected behavior
Work as intended with no trafic

my requests r actually low, but i must post an update, last night i increase the ram on my vm to 16gb, as of now all my issues r gone, ill keep monitoring the situation until tomorrow b4 closing this, but if this was the solution, i hope it works for others as well, i wasnt aware NPM could become so ram hungry lol
