[ClusterLabs] corosync/pacemaker on ~100 nodes cluser

I would like to ask for settings (and hardware requirements) to have
corosync/pacemaker running on about 100 nodes cluster.

For now some nodes get totally frozen (high CPU, high network usage), so
that even login is not possible. By manipulating corosync/pacemaker/kernel
parameters I managed to run it on ~40 nodes cluster, but I am not sure
which parameters are critical, how to make it more responsive and how to
make the number of nodes even bigger.
