This log is kept on writing whenever I switch users.

Please help to solve this.

Answer 1

You gave the answer in your question: you have a ulimit statement inside your /etc/profile which requires root permissions. Since this file is parsed at every login, every non-root user will see that error. Move these settings to a startup script or to /etc/sysctl.conf, if you want these settings to be active system-wide, and you're good...
