I have symon 2.71 installed on two openbsd 3.6 hosts symux is installed
on one. I'm having a problem with symon sending data twice. I'm
receiving errors like below.
debug: good data received from 192.168.25.1:47527
warning: rrd_update:illegal attempt to update using time 1120847609 when
last update time is 1120847609 (minimum one second step)
warning: rrdupdate -- /var/www/symon/rrds/plexfirewall/io_wd0.rrd

These errors are showing up only for the remote host. They show up for
each rrd of the host. A few minutes ago it was doing it very regularly,
errors in log files every five seconds. I've just now changed the
config file and stopped and started symon. It is now happening less
frequently, this tcpdump output shows whats happening.

It looks like this happens about every 10 minutes.
