max/ideal value of items in limits.conf in rhel5?
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 :

Quote:
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.

Code:
*       soft            core            unlimited 
*       hard            core            unlimited
