Have you looked at /etc/login.conf?
The stock values in this file were quite reasonable in 2.2.8, but in
3.x and onwards the values are set to unlimited for almost all
parameters in the default class.
I'm not an expert on this matter, and I don't know if changing the
/etc/login.conf file will help, but I think the old values for the
default class should be put back.
PS! Don't forget to run cap_mkdb /etc/login.conf after editing.
