i want to set limits in /etc/security/limits.conf.My os is rhel 5.2.

It was giving continuous messages in in /var/log/secure like :

Jan 1 09:46:43 yn55 sshd[31742]: pam_limits(sshd:session): wrong limit value 'unlimited' for limit type 'soft'

Jan 1 09:46:43 yn55 sshd[31742]: pam_limits(sshd:session): wrong limit value 'unlimited' for limit type 'hard'

continuously.

I have changed values of priority and nice to "0" from unlimited and messages are not comming. But i want to know what is the ideal/maximum value of these two items? Is 0 value set is correct? To what should i set it to? I want it to be maximum.

    Bu what I read at http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/old/pam-6.html the accepted values represent the filesize in kb, so any non-numeric entry would be invalid. The actual maximum value are based upon system specific limits for each system that it is running on.

    0 generally means no limit, but you also have the option to comment out the effected lines or disable the pam module so that no limits will be imposed in relation to the resource module.
