[syslog-ng] Tests using loggen - not receiving all the packets

Finally getting a chance to revisit this.
I'm still seeing the problem.

If I run loggen like so:
/www/svn/loggen -r 600 -D -I 30 127.0.0.1 514
average rate = 607.51 msg/sec, count=18226, time=30.012, msg size=256,
bandwidth=151.88 kB/sec

I only get around 8k messages:
wc -l /var/log/logzilla/syslog.log
8740 /var/log/logzilla/syslog.log


I've tried bumping up flush_lines and the fifo but neither seemed to
make much of a difference.

Here's my config:
options {
      long_hostnames(off);
      log_msg_size(8192);
      flush_lines(1); # Note: I've tried this up to 1000
      log_fifo_size(35535);
      time_reopen(10);
      use_dns(yes);
      dns_cache(yes);
      use_fqdn(yes);
      keep_hostname(yes);
      chain_hostnames(no);
};

destination df_logzilla {
   file("/var/log/logzilla/syslog.log"
   template("$HOST\t$FACILITY\t$LEVEL\t$TAG\t$YEAR-$MONTH-$DAY\t$HOUR:$MIN:$SEC\t$PROGRAM\t$MSG\n")
   );
};

log {
   source(s_all);
      destination(df_logzilla);
};
