    Can someone help to explain why the AIX ulimit stack setting will indicate hard value of 4194304 when we have set it to unlimited in /etc/security/limits?

    $ ulimit -a
    time(seconds) unlimited
    file(blocks) unlimited
    data(kbytes) unlimited
    stack(kbytes) 4194304
    memory(kbytes) unlimited
    coredump(blocks) unlimited
    nofiles(descriptors) 2000

    But if you look in /etc/security/limits, you can see that it is set

    johndoe:
    core = -1
    data = -1
    stack = -1
    rss = -1
    fsize = -1

    Thanks in advance.

    The value that is being displayed for the stack parameter corresponds to the default stack_hard value:

    From /etc/security/limits:
    * The following table contains the default hard values if the
    * hard values are not explicitly defined:
    *
    * Attribute Value
    * ========== ============
    * stack_hard 8388608

    You would need to explicity set stack_hard to "-1" in /etc/security/limits to get unlimited stack size.

    Hi Debbie,

    Change those limits using smit chuser and change both hard and soft values.
