Description Marian Krcmarik 2016-06-20 16:03:28 UTC

Description of problem:
rabbitmq server starts to fail often during HA stress tests of OSP9. It seems to be caused by regression already reported in upstream and targeted for upstream 36.3 release.

Upstream bug: https://github.com/rabbitmq/rabbitmq-server/issues/812

Version-Release number of selected component (if applicable):
rabbitmq-server-3.6.2-3.el7ost.noarch

How reproducible:
Often

Steps to Reproduce:
1. non-gracefully reset a controller of HA OPS9 environment
2. repeat the 1. step multiple times until one of the rabbitmq servers crashes
3.

This build should fix the issue. Marian, please test.

This particular bug seems to be fixed by the build, I was not able to reproduce it on setup with the updated build. We should push the package into puddle.
