You don't say which version of corosync you are running or on what OS, but on CentOS 7, there is an available update that looks like it might address this (it has to do with scheduling). We haven't gotten around to actually applying it yet because it will require some down time on production services (we do have a few node-locked VMs in our cluster), and it only happens when the system is under very high load, so I can't say for sure the update will fix the issue, but it might be worth looking into.</div><span class="HOEnZb"><font color="#888888"><div class="gmail_extra"><br></div><div class="gmail_extra">--Greg</div><div class="gmail_extra"><br></div></font></span></div>
