I have a job running on a slave. Once the job runs I can see the workspace in
hudson. If I wait overnight and check again in the morning the workspace is gone
with this error:
Error: no workspace

1. The project was renamed recently and no build was done under the new name.
2. The slave this project has run on for the last time was removed.
3. The workspace directory (null) is removed outside Hudson.

Run a build to have Hudson create a workspace.

Turning on more logging, I see the following:

All of these workspaces are owned by a project and should not be deleted.
