mcollective and activemq the 800 node limit

I've been running into the 800 node limit on mcollective and splitting up my nodes into subcollectives. I had a spot where I couldn't split up the nodes, so I started looking at why we were hitting this 800 node wall.

I'm using activemq with the ssl plugin, after turning on all the debugging I could find in activemq, it turns out it's just a simple resource limit problem.

Foreman ruby api adding node to hostgroup or puppetclasses to node

I wanted to apply puppet classes to a node using a script, I started looking at the foreman REST API but stumbled upon the foreman_api ruby. I specified hostgroups in foreman and added puppet classes to the hostgroups. The idea is that I want to be able to change the hostgroups using a script.

Running things through irb this is what I came up with for changing the hostgroups.
