Uncommenting LOG_FILE option in /etc/sysconfig/cgred.conf causes cgred service to fail in RHEL 6

Issue

• Trying to use the LOG_FILE option in the /etc/sysconfig/cgred.conf, e.g. just uncommenting the default line give in the file:

  # Uncomment the following line to log to specified file instead of syslog
  LOG_FILE="/var/log/cgrulesengd.log"
  

[Re]start the cgred service and it fails:

# service cgred start
