Description Joseph Shraibman 2012-05-18 16:23:02 EDT
Description of problem:
In limits.conf, this does not work:
*                -       nproc        9000                                                                                      This does:                                         
0:65535          -       nproc        9000                                                                                                                              

Version-Release number of selected component (if applicable):

Also occurs on CentOS 6.2 with package: pam-1.1.1-10.el6_2.1

How reproducible:

Steps to Reproduce:
1. Use ulimit -a to view your limit, or car /proc/$$/limits
2. Put in limits.conf: *                -       nproc        9000
3. Open new session.  Observe that there was no change
4. In previous line, replace * with 0:65535
5. Open new session, Observe that nproc is now set to 9000

Comment 1 Tomas Mraz 2012-05-18 16:52:28 EDT
That's because the default values set with the * entry is overriden in the limits.d/90-nproc.conf file. You have to edit the default entry there.
