Bug Description

We have a set of cases when corosync hangs and pacemaker gets broken. Corosync hangs in epoll_wait endless loop eating 100% cpu while completely hanging the cluster. This reproduces not so often, but looks like an issue with totempg code. We need to build corosync 2.3.6 which has the fix enabled and ship it with newton repos.
