[knot-dns-users] mod-rrl crashes Knot DNS 3.4.0

Hi I don't know if this is an issue with my configuration or a bug. If I remove the configuration below, knot 3.4.0 starts up fine. When I introduce this config, knot 3.4.0 crashes with OOM, a memory leak. It runs fine on knot 3.3.9. template[default].module = mod-rrl/default mod-rrl.id = default mod-rrl[default].rate-limit = 20 mod-rrl[default].slip = 1 What am I doing wrong or is it a bug? I want to say that I am very content with knot, I've migrated from some servers from powerdns to knot, and things are great. I still run powerdns but primarily knot. Kind regards Dries Pattyn
