How to kill the process: Excessive resource usage

[Jeromero]

Hi all I receive a lot of these.
Now I read on this forum the other thread that I should kill these processes and I found the tutorial on killing the process in linux but I am not sure what PID of 2 I should kill?
The tutorial says:
kill -9 22245

lfd on dwacu.dedicatedserver.com: Excessive resource usage: xtggsnwi (22745 (Parent PID:2442))
Time: Sat Jul 18 10:21:00 2020 +0200
Account: xtggsnwi
Resource: Virtual Memory Size
Exceeded: 524 > 512 (MB)
Executable: /opt/cpanel/ea-php73/root/usr/sbin/php-fpm
Command Line: php-fpm: pool mydomain_com
PID: 22745 (Parent PID:2442)
Killed: No

As I understand I should first kill 22245 and then try to kill parent PID?
kill -9 22745
kill -9 2442

Is this correct?
I am not sure what -9 stands for and can I harm the system by killing these processes?

I don't think killing processes is a good idea. You should first investigate why is this happening. It might be absolutely fine. If you really want to "kill" processes I suggest you to suspend the account which will exist all the processes belongs to the user and then unsuspend it. You can also hire a professional sys admin from System Administration Services to help you investigate it further if needed.

This is indicating that the account noted is using over the threshold of 512mb of vmem (virtual memory) and it notes the php-fpm process as being the culprit. Identifying the cause rather than blindly killing a process is always the best move as suggested by @andrew.n
