executing "restart sampling", appears the following messages in 
/var/log/sampled:

Dec 7 11:10:38 Prefix x.x.194.162 not found in route records
Dec 7 11:10:39 Unable you get route-record will be addr x.x.194.162

Also already a TAC in 28/11 was opened, but so far we did not have reply.

Thanks,
Rodrigo
