the first thing to do is to grab 4.1.1b2. i don't remember anything
like this, but it's easier to work on new problems from most current
the second thing to do is to run dhcpd -6 under gdb.
gdb --args ./server/dhcpd -d [normal other flags]
just make sure to add -d so dhcpd doesn't fork. once in gdb, at its
when (if) you get the heap.c assertion again, type this at the (gdb)
copy and paste the result into an email to dhcp-bugs at isc.org.

the only thing in your config file i'd do differently is use a
CIDR mask on the range rather than an explicit address range. the
current code turns an explicit range into a series of CIDRs. it's
easier and more direct to just specify an address and mask length
than to make it calculate it out.

this means you are getting decline messages, which is a little
