Ubuntu SRU information
[Impact]
OpenStack heat installations may end up with a load of non-functional
heat-engine processes as the controller process fails to terminate them
correctly on shutdown.
[Test Case]
sudo apt-get install heat-engine
sudo service heat-engine restart
<not all heat-engine processes will be terminated>
[Regression Potential]
Minimal; in newton and backports in process to other stable branches.
