Comment 28 for bug 1052535

I have found cases where the metadata service that was running in the namespace is no longer running. I've looked through /proc to find any other processes holding the netns file descriptor open.

Even after confirming that there are no processes holding a file descriptor on the namespace I still cannot delete the namespace. What other resources could be preventing the deletion of these namespaces?

Is it necessary to stop all metadata services in all namespaces? If so, this is not practical.
