With buggy clients (200 renews per second) dhcpd6.leases grow fast to GB size and dhcpd refuses to restart. Mine was 2.4 GB.<br />
<br />
dhcpd: /var/lib/dhcpd/dhcpd6.leases: file is too long to buffer.<br />
<br />
Smaller leases file (388 MB) is parsed and shrinked.<br />
<br />
CentOS 6.5<br />
dhcp-4.1.1-38.P1.el6.centos.x86_64<br />
<br />
They say that the bug was fixed in 4.2.4.<br />
