Multiple "php-fpm: pool www" shouldn't be there?

Question

linux

Hello!
The ps aux --sort -rss command returns data where the lines are like:

www-data 25263  0.1  6.1 435588 62308 ? S 08:15   0:45 php-fpm: pool www

Some. As I think, there should be no more than one line, where there is php-fpm: pool www , and I have this:

Tell me, is it supposed to be like this or is it wrong? If it's wrong, how can I fix it?
The last two lines are generally Debian , although I have Ubuntu, it is not clear what this means ...
Thank you.

Answer 1

Everything is fine. It should be.
If this really confuses you, then you can reduce the pool size in the php-fpm config, but at the expense of performance.
Ubuntu and Debian are direct cousins ​​with full package compatibility. Therefore, in some universal packages, the names of another OS may slip through.
Specifically, in your case, your user name is Debian-+ and exim4 is already running on his behalf
