Some more information I am using the latest version of the saz-rsyslog puppet module, version 4.0.3 https://forge.puppet.com/saz/rsyslog As an example, I have this node called h1pa Yesterday afternoon this node was getting the reported duplicate Class[Rsyslog] declaration error The 12:15am update was the last report of this error The 12:45am update was the first clean update today In fact, I had 0 nodes reporting this error About 9:00am-ish we added a subnet and hostgroup to The Foreman. However we have not added any new nodes, nor changed the configuration to any existing nodes. Then, I started getting the error again The 9:15am update was the first report of this error this late morning The 9:45am update reported this error again My nodes reporting an error of this duplicate Class[Rsyslog] error increased from 0 to 12. All node reports with this error are similar to h1pa node's reports. I am seeing that many of the hosts experiencing this issue yesterday, are now experiencing it again. -RG -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
