We use Oracle EBU and it's always failing on the same file with message id
EBU-7009 (see log excerpt below).  The file is 1660MB in size (quite
large), but our TSM disk storage pool is configured with no size limit.
Oracle says EBU-7xxx errors are relayed from the underlying backup system
(i.e., TSM), so I'm writing hoping someone can tell me what it means.
