Two cores at 100% processor

Hi everybody,

My server is running Linux Debian.
I added the gameservermanagers LGSM script.

Everything works well but I have two hearts out of eight that are consumed 100% steadily.
When I stop the server, both hearts are always consumed at 100%.

I monitor with "htop" but I can not find what tasks might require so much resources.

Do you know how I could do that, please ?
Is there a command to know what are the tasks assigned to each heart ?

 

Are you sure PID is killed ?

 

What is the "PID" ?

EDIT : je suis français pour info
