Hello

This is most likely related to failure to push route to kernel, perhaps
with invalid/strange next hop or iface.

You can enable 'debug all' for kernel protocol. That would at least show
which routes it tries to send.

If you do 'show route', you see '!' for routes that failed to install
into the kernel table.
