What happens when you try to use the option.

I use it with syslog-ng 3.7.1

options {
         log_fifo_size(20000000);
         use_fqdn(yes);
         keep_hostname(yes);
         chain_hostnames(yes);
         time_reap(60);
         time_reopen(5);
         flush_lines(15000);
         flush_timeout(2000);
         stats_level(1);
         log_msg_size(16384);
};


without any problems.
