Comment 1 for bug 1572968

Need to reproduce the issue. We can use 20-nodes environment. New oslo-messaging package with zero driver with timestamping is ready https://review.fuel-infra.org/#/c/19937/ (http://perestroika-repo-tst.infra.mirantis.net/review/CR-19937/mos-repos/ubuntu/9.0/) Need to go though a message chain and find where message stucks.
