Rudder

I upgraded Rudder server from 3.1 to 3.2
right after, I ran rudder agent run, and got following error message:

success  server-roles              Check WebDAV credentials                     The Rudder WebDAV user and password are OK
Formal =  {'message','old_class_prefix'}, Actual =  {'Check if the service httpd is started using ps','service_check_running_httpd','','@{args}'}
   error: While constructing scope '_logger_default'
   error: Fatal CFEngine error: Augment scope, formal and actual parameter mismatch is fatal

error    Rudder agent was interrupted during execution by a fatal error
         Run with -i to see log messages.

(this is the output with -i)
It self corrected as soon as failsafe kicked in.
This is because we changed the signature in ncf, but it take a while for ncf to go from /usr/share/ncf to /var/rudder/ncf/common
