Sporadic exceptions uploading an attachment

[Peter Flynn]

We are seeing this exception pretty often while uploading attachments
(but not all the time).  The file is not uploaded successfully after
seeing this error, but trying again right afterward usually works fine.
Still, we would still like to get to the bottom of this.  Anyone have
suggestions?
