Hey Ken, That's amazing I really appreciate that. I actually have a full configuration that I can share with the list that worked best for me. You reminded me... The examples were partials and had to fill in a lot of blanks to get the timing right etc... I do have a stable CRM/OCF config that I will post on here from our old cluster. Just waiting on building the next one from scratch an making sure the config still plays nice before doing so.
