dhcpd and IPv6

Wed Sep 30 07:08:16 UTC 2009

Hello!

I'm having problems with isc-dhcpd-4.1.0p1. It works fine for 5-15
minutes, but after that it just dies.
It did work fine before the introduction of Windows7.

The machines happily run autoconfigured IPv6, but they don't have a
dns-ipv6-address.

On the cisco-router i have set the M-flag (managed) , O-flag
(other-config) and ip-helper (dhcp-relay).

Below you can see an log-file from '-d' with the final line 
   "dhcpd: heap.c:198: isc_heap_delete: Assertion `index >= 1 && index
<= heap->last' failed."
and the dhcpd6.conf file

Each time it crashes I get a corrupt lease-file; so I do `rm` and
`touch` on it.
Same problem with 4.1.1b2 as with 4.1.0p1

Any hints on what I'm doing wrong?

PS I know that I probably is doing something wrong, but I think it's a
little 
   impolite of it to just die on me (:-)
