Unbound configuration memory leak with python module + register DHCP leases active
0%
Description
Issue reported and diagnosed on forums here: Was able to see evidence of this on SG-1100 and SG-3100.
https://forum.netgate.com/topic/154113/sg-1100-2-4-5-unbound-python-module-dhcp-lease-dns-registration-memory-leak
TLDR: When an unbound python module is configured, and the "Register DHCP leases in the DNS resolver" option is enabled. DHCP clients joining the network cause unbound memory usage to increase each time.
If I disable either the python module, or the option to register leases, things appear to function normally.

This would likely be fixed by also solving #5413 since it wouldn't restart in this case. Though the actual memory leak should be re-tested on unbound 1.13.1 and if it's still present, it should be reported upstream to the Unbound devs.
