These occur when a number of processes need to use a resource in turn. There is a tendency for such bursts of activity to drift towards synchronization, which can be disasterous. In Kademlia all nodes are requird to republish their contents every hour (T_REPLICATE). A convoy effect might lead to this being synchronized across the network, which would appear to users as the network dying every hour.
