Thanks for the update. Barring a very low setting for "max concurrent tasks", I don't see why this could occur, so it appears this could be a production issue. In that case, I'd recommend opening a Public Issue Tracker <http://code.google.com/p/googleappengine/issues/list> thread with label "Restrict-View-EditIssue" (to protect your information) and the following information:
* your app id * the name of the queue * the queue settings * some queue statistics We may be able to determine the root cause of this at that point.
