I am not talking about a crash.  ospfd has a sigterm function that catches
the terminate signal and attempts to do a "clean" shutdown.  Its just not so

I think that's a known issue, zebra should really track what daemon made
each route, and if connection to it drops, delete them.

You can't count on a "clean" crash where the daemon cleans up after itsself.
