Description

This pfsense installation is configured with IPv6 tunnel (hurricane electric) and DHCP for ipv6.
The issue is that file /var/dhcpd/var/db/dhcpd6.leases grows to enormous size and as a result CPU usage is unusually high.
This started with v2.1 and continues after upgrade to v2.2.1
Please note this issue was not happening initially, but begin to happen later.
Attaching leases file and screenshot from RRD performance graph.
CPU is busy with command php processsing prefixes.
