Description Daniel Alvarez Sanchez 2018-07-10 15:19:03 UTC 
+++ This bug was initially created as a clone of Bug #1599766 +++

Description of problem:
OSPD normally configures the controllers hostnames in /etc/hosts (IPv4) but py-amqp will try to query nameservers because there's no IPv6 entry there.

When nameservers are non-existent or unreachable, this leads to 60 seconds timeout when connecting to Rabbit.

The fix got recently merged in py-amqp:

https://github.com/celery/py-amqp/commit/1ad97fb14c0c3c57395ca525932f95a830e51a88

We would need this fix in OSP10.
Comment 1 Luca Miccini 2020-03-03 15:28:15 UTC 
At this time we do not plan to backport these patches to osp10. Please reopen if this needs to be re-evaluated.
Thanks.
