OSPF neighbors remain in "Loading" state for a long time.
/var/log/messages file shows that RouteD daemon has crashed with core dump file:
kernel: do_coredump: corename = "/etc/coredump/compress.sh /var/log/dump/usermode/routed.PID.core
kernel: do_coredump: argv_arr = /etc/coredump/compress.sh
kernel: do_coredump: argv_arr = /var/log/dump/usermode/routed.PID.core
RouteD sends Link State Request (LSR) for its own LSAs, but does not accept them when neighbor resends them (OSPF trace shows "OSPF LSA: Received own LSA ... must flush").
