Tracking: pihole-FTL.log spam after adding invalid regex to domain list
Noticed when testing new 2022.04.3.
To repro :
-
tail -f /var/log/pihole-FTL.log
- Add an invalid regex to the domain list (i.e
[[[
) - Watch the fireworks
Doesn't appear to happen on bare metal - so seemingly Docker specific. Probably to do with s6?
