Doh! I should read the log more carefully, the hint is there:
new ktable rdomain_0 for rtableid 0
listening on 0.0.0.0
change to/from route-collector mode ignored
RDE reconfigured
In other words the daemon came up in route-collector mode and so no pathes
are validated. Figured it out at the airport by just looking at the code
and swearing.
Diff is untested but I guess everyone agrees that a bit more memory
inizialisation could help.
