forked process defunct
When executing knot resolver in the docker container environment, defunct it by forking the process with 2 or more as the startup option. Moreover, since the timing to defunct is not fixed, I can not confirm what is the starting point.
env:
- base image: arm64v8/alpine:edge
- knot resolver 3.0.0
