disable mcollective?

edit

Hello all,

I'm just starting with PE 2015.2 and I have an all in one puppet master managing 8 nodes. It's simply managing ntp for these nodes at present, but a developing elasticsearch problems alerted me to the fact that mcollective is doing something horrible to my nodes. Basically it's using up all the memory, the box starts swapping like crazy and then everything crashes.

i want to stop mcollective at the moment while I assess what is going on, however this doesn't seem possible. a basic install of PE 2015.2 seems to start mcollective and it's not possible to stop from the node itself. My questions are these,

1. do I NEED mcollective (until I've got a chance to really troubleshoot the source of the issue) being that I don't need live management (or whatever it's called now in PE 2015.2).
2. How do I turn it off?

nodes are all ubuntu 14.04 LTS as is the puppet master.

EDIT:

I've found in the logs the issue. this is after fresh install of a puppet server 2015.2 and nodes were added by running the agent curl command from 'sign certificates'. Therefore total default install produces this result.
