We noticed a few, unusual things: -> regardless of the link tested (kif or fastd3) and regardless of the node (node1, node2) small interruptions (loss-peaks) are appearing. -> These peaks appear almost synchronous, a few "noise" comes from different vpn-links and node-wan-uplinks. -> Since all links are wired, radio-noise won't have an impact -> The losses appear in batman-adv 2011.2.0 as well as in batman-adv 2012.4.0. Thus I suspect that batman-adv is triggering theses interruptions.
If you believe batman-adv is the culprit, please remove batman-adv from your test setup and repeat the exact same test. Otherwise we move into the realm of speculation.
Haven't heard of any "peak loss" due to batman-adv.
