Would like to know who kill process

Hi all,

I'm a new developer of OpenWRT.
I have a question as below:
"How to know who kill the process."

I can't to get the answer from logs.
and
seems no info about this after I search keyword in code.

Any suggestion for adding log to know this?

Thanks.

BR,
Hank
