Package: isc-dhcp-server Version: 4.3.5-4 Severity: important Tags: ipv6 Dear Maintainer,
I use isc-dhcp-server as a DHCPv6+DHCPv4 server in a home network with mostly Windows and a few Linux and Android clients. After upgrading to 4.3.5-4, I noticed that the DHCPv6 server would die after a while, with no error messages in syslog. Meanwhile, DHCPv4 keeps functioning without a problem. Trying to reproduce this today, I found that running the "ipconfig /release6" and "ipconfig /renew6" commands in Windows, to release and reacquire the lease respectively, is enough to trigger the crash. I do not have this issue after downgrading to 4.3.5-3.1. Below is the output from running dhcpd in foreground mode. Thank you! ------------------------------------------------------------------------------- # /usr/sbin/dhcpd -6 -d -tf dhcpd6-trace -cf /etc/dhcp/dhcpd6.conf eth0_lan eth0.2 eth0.3 Internet Systems Consortium DHCP Server 4.3.5 Copyright 2004-2016 Internet Systems Consortium.
