RRA files not updated or created

[Mr_V]

hi,

this thursday my cacti stopped to update RRA files unexplicabbly.
I upgraded to cact-0.8.6g & cactid-0.8.6f-1. stills not updating rra.
I've maked a backup of old rra files so lets cactid to make new ones.. but no new rra files created.
When i run cactid manually i see that him grabs the data from snmp & other sources but doesnt says anything about rra's.
When i run poller.php it seems to grab the data too but no rra update/create.

I noticed with 'strace' the rrdtool process that him doesnt do anything.. probabbly because no data is passed when running 'rrdtool -' from cacti poller. Also poller.php starts to waste all the CPU

root 24090 0.0 0.0 2268 548 pts/1 S 18:50 0:00 /usr/monitor/rrdtool-1.2.11/bin/rrdtool -
But no changes or new rra's.

cactid 0.8.6f-1
cacti 0.8.6g
rrdtool 1.2.11


any idea ?
rrdtool is already on the $PATH variable
