Pavlo,
Here is a link to one of the stacks. It is fairly simple just some
routers/nets/subnets. The description is a bit odd perhaps, but legal.
I've changed the template to not point at IPs at internal DNS.

I've not been able to reproduce with this template running my local Juno
2014.2.2 or a recent devstack, but I'm sure you can.
I created and deleted this in a loop about 5 times and it finally
failed to delete on the last run. Now that it is stuck in
DELETE_FAILED no amount of deleting will help. I'm concerned that a
template this simple can get stuck like this.
You should be able to delete the underlying resources using the neutron
command, then delete the stack.
I will have stack_abandon enabled next week as it just landed in
Puppet: https://review.openstack.org/#/c/168157/ and will plan on
trying that then.
We've needed a series of workarounds for neutron resources as there are
often implicit dependencies created which are not declared in REST
create calls. Its likely you've discovered some more implicit
dependencies which we need to handle. Could you please raise a bug [1]
with the following?
- the above pasted template
- the heat event-list of the DELETE_FAILED stack
- the heat stack-show of the DELETE_FAILED stack

Hi Matt,
if it would be feasible/appropriate, could you provide us with
templates for stacks that show this behavior (try to get them with
"heat template-show <stack-name-or-id>")? This would help us to
test and understand the problem better.
And yes, just the day before I was contacted by one of my
colleagues who seems to experience similar problems with
Juno-based OpenStack deployment (though I did not had a chance to
look through the issue yet).

Nobody on the operators list had any ideas on this, so
re-posting here.
We've been having some issues with heatdelete-stack in Juno.
The issues generally fall into three categories:
1) it takes multiple calls to heat to delete a stack.
Presumably due to heat being unable to figure out the ordering
on deletion and resources being in use.
2) undeleteable stacks. Stacks that refuse to delete, get
stuck in DELETE_FAILED state. In this case, they show up in
stack-list and stack-show, yet resource-list and
stack-delete deny their existence. This means I can't be sure
whether they have any real resources very easily.
3) As a corollary to item 1, stacks for which heat can never
unwind the dependencies and stay in DELETE_IN_PROGRESS forever.
Does anyone have any work-arounds for these or recommendations
on cleanup? My main worry is removing a stack from the
database that is still consuming the customer's resources. I
also don't just want to remove stacks from the database and
leave orphaned records in the DB.
