hmm funny
i guess we in vienna just could not believe that others may have even more
hops, as we already suffer very regulary ,..
but maybe we just have better monitoring, ..
or we just don`know how much others suffer from this,..
or maybe the 5G backbone introduces problems not known to other meshes,..
or vienniece just love to complain,..
whatever, best would be to stop us and other from suffering from loops *g
but i assume taht in the last months loops mostly come from implementation
bugs
which cause links which do no time out,..
and from inconsistent kernel/olsr routing tables, which simply creates loops
or blackholes
