dhcpv6 leases file corruption

Tue Apr 5 19:57:24 UTC 2011

Hi folks, not sure if this is a bug or something I'm doing wrong.
During the last two or three upgrades of dhcp, when starting the service I get:

/usr/sbin/dhcpd -6 -cf /etc/dhcpd6.conf -lf /var/state/dhcp/dhcpd6.leases eth1

Seems information is getting written to the leases file and missing
the ending semi-colons?

I don't know if this is due to the way I kill the dhcpd process (kill
`cat /var/run/dhcpd6.pid`), or an actual bug in dhcpd.

Thoughts?
