Release blocker: Moving management vip breaks rabbitmq sessions

 

Team,

Me and Ryan have spent all day investigating
https://bugs.launchpad.net/fuel/+bug/1285449

What we have found so far confirms that this is a critical bug that
absolutely must be resolved before 4.1 is released.  I have documented
our findings in the bug comments, someone please take over the
investigation when you come to the office tomorrow morning MSK time.

I have a feeling that once the root cause is found, the fix will be
low-impact and will involve either change in HAProxy configuration for
RabbitMQ, a patch/upgrade of HAProxy or kombu, or something similar.
But first we need to understand what exactly breaks, and why this only
affects some services and not all of them.

Thanks,
