Description Alberto Rivera Laporte 2018-11-29 17:12:34 UTC
Description of problem:


The Red Hat Openstack Platform 13 Directors Installation and Usage Guide[0] contains what I suspect are deprecated troubleshooting functions regarding restarting the Heat API in the Director Troubleshooting/Tuning the Undercloud section [0].

--------------
Chapter 13
Section 13.8
-------------------

Section content: 
-------------------
The openstack-heat-engine and openstack-heat-api services might consume too many resources at times. If so, set max_resources_per_stack=-1 in /etc/heat/heat.conf and restart the heat services:

$ sudo systemctl restart openstack-heat-engine openstack-heat-api
-------------------


Issue: 
-------------------
In Red Hat Openstack 13 the heat-api service is configured as a WSGI application under the control of Apache. Restarting the openstack-heat-api service as instructed by the troubleshooting guide will cause issues with port conflicts as it attempts to bound to port 8004 which is already bound by the apache/wsgi interface of the openstack-heat-api and will not yield the desired results.
