Undercloud stack failing to come up - overlimit ram quota exceeded

[Michael Kerrin]

Undercloud stack is failing to come up.

When we do heat stack-show undercloud we get the following message:

A continuous build job that I have running every 3 hours last succeeded at Mar 3, 2014 6:45:39 AM GMT. So any change causing this is likely to have been made since then.

I'm pinning back repositories to try and locate the repository in which the breaking change was made.

[Jon-Paul Sullivan (jonpaul-sullivan)]

Pinning back service team repositories makes no difference.

Pinning back tripleo-incubator, tripleo-image-elements, tripleo-heat-templates and diskimage-builder appears to have done the trick.

[Jon-Paul Sullivan (jonpaul-sullivan)]

Tracked the problem down to the following:
git revert --no-edit c2eaf87
[master 44ba40c] Revert "Store node details in the JSON datafile"

Reverting that commit (and using master of all of tripleo-image-elements, tripleo-heat-templates, diskimage-builder) removed the quota error in bringing up the undercloud.
