---------------------------------------------------------------------- 
I would bump up the severity to major actually. This is also happening with
1.4.26, but more to the point it even killed a customer's internet
connection (I do hosted PBX) by seemingly flooding his Internet links with
something (not sure what, likely qualify messages).  I had to restart
Asterisk before link usage became normal.

Usually it's just a double "UNREACHABLE" message, but that time there were
about 15 similar messages every few seconds, going from UNREACHABLE to
reachable (x ms) in quick succession.

I think this seemingly benign problem is hiding something that could hurt
somebody using "qualify" occassionally.
