ERROR Unable to connect to rrdcached: Connection refused

Troubleshooting

Hi, I updated from 1-4.0.p31 to 1-6.0.p8 and the graphs only showed data for about 20 minutes to 1 hour after a reboot then stop displaying data completely.

I noticed this in the prefdata.log

RRDs::update ERROR Unable to connect to rrdcached: Connection refused

Any ideas how to troubleshoot further?

Thanks
