I'm trying to "undelete" records following the Workbench steps in this article and am getting this error when I try to "undelete" with a csv file:

"Application Error: An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details."

However, it seems to delete a few hundred records. Does anyone know how many records you can "undelete" at one time? I have 15k recoreds to recover.
