EAGAIN
The uid does not match the current uid and uid brings process
over it’s NPROC rlimit.

It’s the same error that was returned to fork()

EAGAIN
It was not possible to create a new process because the caller’s
RLIMIT_NPROC resource limit was encountered. To exceed this limit,
the process must have either the CAP_SYS_ADMIN or the
CAP_SYS_RESOURCE
capability.

more /etc/passwd | grep mark
mark:x:500:500::/home/mark:/bin/bash

from nginx configure

user mark;
worker_processes 1;

and this is how i start nginx
sudo /opt/local/sbin/nginx -c
/home/mark/work/infrastructure/nginx_staticfarm.conf

am i doing something wrong?

do you know how do I give these capabilities to the processes?

What does

ps -U mark | wc -l

ps -U mark | wc -l
278

What do

limits
or
ulimit -a

ulimit -a

There is no limit for processes and you run not too much processes -
278.
I have no idea why Linux returns EAGAIN.
