I think that php-fpm needs more than 8 MB RAM per process.
On my machine they currently around 50 MB per process.
And you do not have the guarantee that they will not need more
than this.
In your first mail the warning says that you are currently using 143
child processes. Why do you want to start 4000 at the beginning?
If you do not want to have a dynamic adjustment of the fpm processes,
this is what 'pm = dynamic' does, that you can try 'pm = static'.
