## Summary musl 1.2.5 includes [several fixes to DNS over TCP](https://www.openwall.com/lists/musl/2024/03/01/2), which appears to be the root cause of #6116. This approach is a bit janky, but according to codex: > On the Ubuntu 24.04 runners we use, apt-cache policy musl-tools shows only the distro build (1.2.4-2ubuntu2)" We should build with this version and confirm. ## Testing - [ ] TODO: test and see if this fixes Azure issues
