Every now and then the network is flooded with what I assume is looping packets. 200-300MB of bandwidth per node over 10-45 minutes (normally < 20 KB/s, idle). Most if not all nodes participate in the spike. Some nodes just have a spike on output, some only on input.

Oh, that's quite a lot. First, which version of tinc are you using?
Which Mode (router or switch) are you using? Are you bridging the VPN
interface with the LAN interface on any of the nodes?
