The size of both catalog files are exactly the same (I am referring to this file: /var/lib/puppet/client_data/catalog/server1.mydomain.example.com.json ). The only difference inside the file is the order of items in the json arrays. I have checked carefully, the order in which Rsyslog classes definitions are appearing in '.data.edges[]' and '.data.resources[]' is in the same order of appearance between catalogs from both servers, however they are intermingled with definitions from other modules differently - with this I mean the definition for Class[Rsyslog::Config] appears as element .data.edges[23].target in the primary master (that is successful), but as element .data.edges[4].target in the secondary master (that fails with duplicate declaration), though no other Rsyslog class comes before this one in each catalog. So the only difference I can see between the two puppet servers is the order of the overall elements in the catalogs' json hashes and arrays. Could this be a cause of the duplicate declaration error? And if it might be, how do I get the definitions in the catalog to compile into the correct order that would prevent the duplicate declaration error? -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
