splay breaks many things, including puppet kick. It simply won't work until you break splay out to only affect normal running. I tried enabling it, and found that it simply didn't affect the systems enough. I am deeply curious as to why you are avoiding the main question here: 1. How does puppet decide when its 30 minutes is up? Is this stored in a file somewhere? 2. How can we change its calculation? (can we edit a file, run a command, …?) > On Nov 3, 2011, at 8:38 AM, Nigel Kersten wrote: >> On Thu, Nov 3, 2011 at 8:36 AM, Jo Rhett <jrh...@netconsonance.com> wrote: >> For a long time it appeared that run cycles were fairly balanced -- a few >> every 30 seconds over the 30 minute period.
