i want to set stack size limit to unlimited for soft limit for particular user on RHEL5.3

i set to hard limit to unlimited and it's showing if i give ulimit -Hs but if i set unlimited or any other value for soft limit in /etc/security/limits.conf it's not getting reflected.
i closed the session and re-opened it also.

could it be that there is a ulimit command in the user's .profile resetting the limit to the old value?

What is the immediate effect of "ulimit -Ss unlimted"? Check with "ulimit -Ss"!

... and is there a /etc/security/limits.d/ directory? If so, what's in there?

Further, please try "-1" instead of "unlimited" in limits.conf. Some OS'es don't suppoert "unlimited".
Also remember that you'll have to set both hard and soft values in limits.conf.

there is no ulimit command in user profile.
after logging in i have set  " ulimit -s unlimited " and it's showing stack size as unlimited, but if open new session it's going to old setting.
i have set up value for both soft and hard limit, but hard limit only permenatly getting reflected but not
soft limit.

/etc/security/limits.d is empty.

Set it under user's home dir .bashrc file.


This will enable the ulimit in both logon and nologon Terminals.

What have you actually got in the /etc/security/limits.conf file?

You need 2 lines in there as follows:
* soft core unlimited
* hard core unlimited
