Redis Service does not start in slave mode
Symptoms
A Redis service is using the 'slaveof' command in the configuration file. Yet the service starts as a master. When the slaveof command is issued interactively, it does work though and the service goes into slave mode.
Reason
When the 'slaveof' command had been uncommented in the configuration file, a space has been left before 'slaveof'.
Resolution
Remove any blanks or other characters so that the line directly starts with 'slaveof'.
