Hi there,
Since the PR is merged, the option template seems to be malfunctioning.
By applying puppet, the following changes are applied on the maxconn option :

-  maxconn 150
+  maxconn 0
+  maxconn 1
+  maxconn 2
+  maxconn 3 
+  maxconn 4
+  maxconn 5
+  maxconn 6
...

Until maxconn 149
I'm using this call :

options => {
  'maxconn'       => 150,
}

by trying to set the value to String type

options => {
  'maxconn'       => '150',
}

The problem seems to be resolved.

I tested the commit before this PR and nothing to report. I think the change of template engine induced this anomaly.
Or maybe it's a normal breaking change ?

Thanks
