The question is. How often you get this lines? If there are only few of 
them, it's nothing to worry, it just means that corosync message(s) 
was/were lost and Corosync tries to resend them again.

But if you have a lot of these, followed by new membership forming, it 
means you ether:
- are using multicast, but messages got lost for some reason (usually 
switches) -> try UDPU
- MTU of network is smaller than 1500 bytes and fragmentation is not 
allowed -> try reduce totem.netmtu
