Rudder

I upgraded on 3.2, and got 1 node out of 3 that did not upgrade its ncf.conf.cache file, resulting in the following errors

2015-11-24T09:55:02+0000    error: /default/rudder_directives/methods/'Configure network parameters/Configure network parameters'/default/Network_configuration/methods/'method_call'/default/file_ensure_keys_values/methods/'report'/default/_log/methods/'wrapper for _logger_default'/default/_logger_default: While constructing scope '_logger_default'

The /var/rudder/ncf/local/ncf.conf is correct, so I don't know why it fails

Interestingly, the 2 nodes that succeedeed at updating it are both policy_server, and don't any meta techniques applied to them
