Public bug reported:
Bugzilla reference: https://bugzilla.redhat.com/show_bug.cgi?id=2233797
This issue has been reproduced using the Tobiko framework. The test,
that is executed several times, is rebooting the controllers and thus
the Neutron API. Randomly, one Neutron API worker fails during the event
method execution "post_fork_initialize", during the "_setup_hash_ring"
call [1].
Regardless of the result of the method "post_fork_initialize", the API
worker starts. But in this case there are some methods (mainly related
to the OVN agents) that are not patched and thus the result of the API
calls ("agent show", "agent list", etc) is wrong.
This bug proposes:
* To properly handle any possible error in the "_setup_hash_ring" call.
* To log a message at the end of the "post_fork_initialize" method to check that this event method has finished properly.
* To catch any possible error during the "post_fork_initialize" execution and if this error is not retried, fail and exit.
