This generally happens if the network is slow or congested. It is 
corosync saying it needs to resend some messages. It is not uncommon for 
it to happen now and then, but that is a fairly large amount of retransmits.

Is your network slow or saturated often? It might be that the traffic 
from the join is enough to push a congested network to the edge.
