hostmonitor hits corosync's scaling limits since it relays on hosts listed in "Online" of crm_mon command's output to check whether each compute host works well or now. Pacemaker-remote which doesn't relay on corosync's connection has been released since pacemaker-1.1.11. If hostmonitor also checks each host status with Pacemaker-remote, it'll be released from the corosync's limits.
