We are getting some strange error when re-publishing the same page. The page was published successfully the first time and we can see the page from presentation server. It failed with the following error (see below) when we tried to publish it again (no change to page). The page ran OK within template builder and we got the correct html output, it failed in the last committing deployment step (Prepare Transport, Transporting, Preparing Deployment and Deploying are all successful). Once it fails to publish the second time, it always fails to publish, and we can't un-publish it either. Also when we make a copy of the failed page and create a new page, we can publish the new page first time, the new page then fails to publush the second time with the same error.

Does anyone know what would cause this error? any help would be greatly appreciated.

Here is the error msg:
