Bug Description
A team within Microsoft is running the linux-azure Ubuntu kernel on a large AI cluster. They are hitting an issue which is resolved by the following commit:
https:/
The bug is that threads can get stuck in the kernel. This bug can happen when removing network namespaces. This is something docker swarm does anytime it removes a container.
Commit ebaf39e6032f was added to the mainline kernel tree in v4.20-rc6. It was not cc’d to upstream stable, so only v4.20-rc6 and newer kernels will have it.
A test kernel was built with this commit, which resolves the issue.
