Try to identify the resource(s) that do not have a status of CREATE_COMPLETED or UPDATE_COMPLETE and create a list of those resources. The problem might be related to one of those resources.
To find the resource(s) that do not have a status of CREATE_COMPLETED or UPDATE_COMPLETE go to this section of the UI:
When you find the problem related with one of the resources then try to solve thatt particular problem and see if that solves the problem with the stack.
Solution 2.2
