Those certainly need fixing but are probably not the cause. Also why do
you have these values below set?
max_network_delay: 100
retransmits_before_loss_const: 25
window_size: 150
I'm not saying they are causing the trouble, but they aren't going to
help keep a stable cluster.
Without more logs (full logs are always better than just the bits you
think are meaningful) I still can't be sure. it could easily be just
that you've overwritten a packaged version of corosync with your own
compiled one and they have different configure options or that the
libraries now don't match.
