help - i'm trying to increase a user's process limit i've increased it in /etc/security/limits.conf. But when I log in as that user, and run 'ulimit -u 1024' (a bash builtin), I get 'operation not permitted' Also, even with the limit of 1024 set in /etc/security/limits.conf, 'ulimit -a' still reports a limit of 256 processes. What do i need to do to allow this user a maximum of 1024 processes? Thanks for your help David
