[knot-resolver-users] Preload module with mutliple instances of kresd

Hello, I'd would like to ask for help with preload module. The issue is that when running multiple instatnces of kresd under systemd usualy just one of them is able to start correctly. The other hangs and fails to start. The config is just copy/paste from the documentation: modules.load('prefill') prefill.config({     ['.'] = {         url = 'https://www.internic.net/domain/root.zone',         interval = 86400, -- seconds     } }) Starting instances in a sequence does not help, the 2nd one hangs - and only if the 1st one is killed/stopped the 2nd one goes on and processes the root zone. Did I miss something in the documentation? With regards Ales Rygl
