Polling OK but RRD updates with Unknown value

[Jester]

Hi folks,

Here's my Cacti log output :

03/27/2012 11:16:06 AM - SPINE: Poller[0] Host[44] TH[2] DS[401] SNMP: v1: 192.131.24.40, dsname: bladecent_fan1, oid: .1.3.6.1.4.1.2.3.51.2.2.3.1.0, value: 45% of maximum
03/27/2012 11:16:06 AM - SPINE: Poller[0] Host[44] TH[2] DS[402] SNMP: v1: 192.131.24.40, dsname: bladecent_fan2, oid: .1.3.6.1.4.1.2.3.51.2.2.3.2.0, value: 46% of maximum

And then :

03/27/2012 11:16:06 AM - POLLER: Poller[0] CACTI2RRD: /usr/bin/rrdtool update /var/www/cacti/rra/test_bladecent_fan1_401.rrd --template bladecent_fan1 1332839752:U
03/27/2012 11:16:06 AM - POLLER: Poller[0] CACTI2RRD: /usr/bin/rrdtool update /var/www/cacti/rra/test_bladecent_fan2_402.rrd --template bladecent_fan2 1332839752:U

It's been working fine for severall months but not anymore and I can't figure out why !

Any clue ?

Cheers !

This is which version of cacti, spine?
Does this happen when using cmd.php instead of spine?
