Depends on the specific kind of resource limit: open file descriptors,
maximum data size, stack size,... (see the ulimit/limit command of your
shell and ulimit(3)).

Take a look at the login.conf(5) man page. Something like

  $ cat /etc/login.conf 
  default:Default class:\
        :openfiles=256:

should change the number of open file descriptors per process for all
users with an empty 'class' field in /etc/passwd.
