Heat is certainly popular, though not as popular as the core services.

I wonder, could you try setting this in your heat config:

convergence_engine = true

This will switch Heat to using the experimental convergence engine,
rather than the legacy one. One of the main goals of convergence is to
make Heat lighter weight. It has also received most of the attention
over the past few cycles, and I wonder if the refactoring done on Heat
to support it has not taken into account something in the legacy flow.

Anyway, if that does fix the problem, perhaps report that as a bug here:

https://launchpad.net/heat/+filebug

Might create a compelling case for switching it on by default in Newton.
It's not too late! :)

Why does it have to be an "or" question? Are they really that different?
