Have you tried looking at traffic on the DHCP6 server with tcpdump:
[0:root at elmo clamav]$ tcpdump -n -i lan4 portrange 546-547
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lan4, link-type EN10MB (Ethernet), capture size 262144 bytes
14:49:26.162028 IP6 fe80::74b4:e117:e83:e565.dhcpv6-client > ff02::1:2.dhcpv6-server: dhcp6 renew
14:49:26.164029 IP6 fe80::6ef0:49ff:fe0a:1e54.dhcpv6-server > fe80::74b4:e117:e83:e565.dhcpv6-client: dhcp6 reply
14:50:26.595666 IP6 fe80::f976:c419:fe5b:11c.dhcpv6-client > ff02::1:2.dhcpv6-server: dhcp6 renew

Substitute your interface for lan4.
