Jenkins sometimes shows logs and artifacts from one project in anothers view.

Config:

• 3 Projects, cloning from git and running batch files
• Global workspace is "D:/jenkins/workspace"
• Project workspace is "D:/jenkins/projectname" (no special chars or spaces)

When building these projects, it sometimes shows the wrong build logs (console output) for the projects, and lately started to show one projects artifacts under another projects artifacts, under lastSuccessfullBuild. The workspace viewer shows the correct files though.

This makes it impossible to automatically fetch the jobs using for example wget.
This has happened on the XP machine and on the Win7 machine, usually starts a few days after setting up the box. Both are Masters with no slaves. Projects run three batch files, first and last run a powershell script, middle one runs a single exe that builds the releases.
The chance for it to happen increases when building more jobs one after the other with little time between them (we don't build them concurrently).
