Yup. At least this is *supposed* to have root permissions.
Isn't it a bad practice to allow a login for a user with root permission? I thought it was a best practice to login as a non-privileged user and then switch to a privileged user using su, or execute a command with sudo.
You might try reasking the question over in the Unix forum to get some more specific help.
If all else fails, can you clean up files elsewhere (e.g. /tmp) to free up some room without having to touch the log files?
