[pkg-dhcp-devel] Bug#722294: isc-dhcp-server: ISC DHCPv6 Server crash

[M. Braun]

Package: isc-dhcp-server
Version: 4.2.2.dfsg.1-5+deb70u6
Severity: important

Dear Maintainer,

I'm running the ISC DHCPv6 server locally on multiple interfaces
and am seeing frequent crashes while handling DHCPv6 RENEWAL packets.
I'd rather not expect ISC DHCPv6 to crash.
I verified that the system is not running out of memory or disk space.

Please find attached a core dump of the crashed dhcpd.

Regards,
 M. Braun
