Problem description:

Every 5 minutes I am seeing the following in /var/log/auth.log:

Feb 6 11:22:02 xbian sudo: pam_unix(sudo:session): session opened for user root by (uid=0)
Feb 6 11:22:02 xbian sudo: pam_unix(sudo:session): session closed for user root
Feb 6 11:27:02 xbian sudo: xbian : TTY=pts/6 ; PWD=/home/xbian ; USER=root ; COMMAND=/usr/local/sbin/xbian-config reboot


There are no corresponding entries in /home/xbian/.xbmc/temp/xbmc.log for these notices and XBMC is
not restarting. Does anyone know what is happening or how to stop this?

How to reproduce:
unknown


Thanks,

George
