Ticket 49388 - repl-monitor - matches null string many times in regex
    
    Bug Description:  When using a wildcard(*) for the hostname, some of the
                      regex's for parsing the various configurations throws
                      out warnings.
    
    Fix Description:  When a wildcard is detected reset the hostnode variable
                      to nothing.
