net-snmp has not ipv6 support enabled. EXTRA_OECONF +="--enable-ipv6" should be added. Note that that will trigger printouts like error on subcontainer 'ia_addr' insert (-1) Searched for solutions for this and some seems to indicaate that it is a leak in net-snmp but others indicate that -Lsd in SNMPDOPTS should be changed to -Lsd6 Agree that that will hide the issue but this does not address the root cause
