TL;DR musl attempts to query every resolver in parallel. This can cause problems if: - If your resolvers are VIPs for the same process or machine, you can triple you DNS load and overload some crappy DNS dispatchers - If you try to use multiple resolvers that resolve the same names with different records, you can kind of make it work with glibc but you will have severe problems with musl. This is a bad idea in the first place though
