V2.3 Getting rrd error in logfile same as closed bug#6053 [Solved]

[illern]

Hello!

Upgraded one of my boxes yesterday from 2.2.6 to v2.3 -release (amd64).

Almost every startup or reboot i get some error messages about update of rrd graph that fails.
One message for every graph.

php-cgi 		rc.bootup: The command '/usr/bin/nice -n20 /usr/local/bin/rrdtool update /var/db/rrd/system-mbuf.rrd N:U:U:U:U' returned exit code '1', the output was 'ERROR: /var/db/rrd/system-mbuf.rrd: illegal attempt to update using time 1460567396 when last update time is 1460572889 (minimum one second step)'

This one is from a reboot only and the timestamps are more then 5000s apart.
The bug#6053 have the same error and is closed.

/Best regards illern.

could it be that your BIOS-time is 1.5 hours into the future ? setting it to the correct time will most likely remove the error on boot (better a minute in the past, then the future)

graphs are started before NTP kicks in to adjust the clock to the correct time.

Thanks heper for pointing me in the right direction.

This pfsense is running on a vm machine under virtualbox.
There is a setting for the bios clock if it will send UTC or local time to the vm machine.
I had it on Local and it needed to be on UTC for pfsense.

Changed it and waited out the last update time of rrd and then the reboots are ok.

I believed my clock was Ok since I have ntp on the host server and ntp in pfsense.
