without any tweaking :
# netstat -s -p udp

       0 with bad data length field
       0 with bad checksum
       20003 with no checksum
       142075741 dropped due to no socket
       1152246 broadcast/multicast datagrams dropped due to no socket
       1729027 dropped due to full socket buffers
       0 not for hashed pcb
       605901007 delivered
       801662 datagrams output
it's been up for a bit, and I don't use syslog but minirsyslogd, which is in
the ports tree I believe.
