Re: v5.8 - Error opening specified endpoint ""

Can you try running without '-c <config_file>' option? If you see
using 'strace' snmpd default
starts listening on udp:161 and then reads the config file and tries
to listen to the
same udp:161 which causes issues and once you kill snmpd both of them are gone,
hence not seen in netstat.
