That is ok.  That means the HSLS daemon has connected to Zebra.

hsls_router_run() calls event_dispatch(), which repeatedly calls
event_loop(), forever, or until there are no more events scheduled, or
until there is an exception from which event_dispatch() cannot recover.
libevent has some documentation.  On NetBSD, there is a manual page.

BTW, I am using version 1.0c of libevent.  You may need a later version.

Right, one event is receiving a packet.
