If I do su "user" or start any process as "user", limits have no effect. How can set limits to "user"? In my case I want to set memory limits to user nobody which execute perl.

Process limits are available, and are usually set by login classes.
See the man page for login.conf.

Yes, but limits applied if "user" use login. If I do su "user" or start any process
as "user", limits have no effect.
How can set limits to "user"?
In my case I want to set memory limits to user nobody which execute perl.
