How to reduce the number of open descriptors that are displayed by the fs.file-nr parameter?

Question

linux

Actually a subject. I ask you to tell me how to find a process that has gobbled up an incredibly large number of open file descriptors? Maybe with the help of lsof, ps?
example from real life:

cat /proc/sys/fs/file-nr
5927920	0	6577798

Here, from memory, I quickly sprinkled it, crookedly, but you caught the essence, I think.

#!/bin/bash

for i in `ps aux --no-header | awk '{print $2}'` ; 
do
        echo `lsof -p $i | wc -l` " - " `lsof -p $i | awk '{print $1}'`
done
