RRD not being created

[scuda]

system: Debian lenny
Cacti: 0.8.7b-2.1+lenny2
rrd: 1.3.1-4 (this is latest in debian)
I have searched the forums and have not been able to find a solution. I am not receiving any error messages but the rrd's are not being created. The data source appears to have been created but it's not: Anybody have any thoughts? I have manually enter this using cactiuser, it creates the rrd so permissions should not be an issue. Could it be the rrd needs to be downgraded to 1.2? setting 1.1x or 1.2x, I have tried both.

/usr/bin/rrdtool create \
/var/lib/cacti/rra/m1-corea_traffic_in_729.rrd \
--step 300 \
