Larrd data problem, Implementation Assistance - New User

Almost forgot, I had another problem. My larrd data get's the

following errors on the Hobbit Server:

update using time 1162503307 when last update time is 1162503307 (minimum one second step)

2006-11-02 15:35:07 RRD error updating /usr/local/apache2/htdocs/hobbit/data/rrd/iesx004/netstat.rrd from 192.168.20.33:

Template contains more DS definitions than RRD

So, how do I fix this and still keep my old larrd data. I get the same message

with my iostat and vmstat rrd coming in from the larrd BB clients.

Thanks.James
