#su -
su: cannot set user id: Resource temporarily unavailable

After searching and googling few minutes, i found a quick resolution to fixing this issue.
This is all about VPS limit.

Edit limit.conf below or change if needed.
#vi /etc/security/limit.conf
#### add/change on these line below:
* soft nproc 2047
* hard nproc 16384
* soft nofile 2048

After that try to relogin using a normal access user and then try to get su -
this should fixed your issue.

  2. The file to edit is not /etc/security/limit.conf. It is /etc/security/limits.conf

  3. # su -
    su: cannot set user id: Resource temporarily unavailable OR it continues to ask for password (even though I'm putting it in correctly and have even re-entered passwords into GoDaddy's control panel for deanflory AND WHM for root's password
    OR
    # sudo su -
    RESPONSE: sudo: PERM_ROOT: setresuid(0, -1, -1): too many processes


    The issue was resolved by editing the /etc/security/limits.d/90-nproc.conf file to allow root more open files. After that, sysctl -p /etc/sysctl.conf was used to make it take effect.
