The test version of "current" that you sent me does not generate those errors. Your routine to rewind the tape is not activated. Attached you will find a backup script and the associated errors generated from it using today's version of RELENG_3. More errors than usual are generated now. It used to only complain about the PREVENT/ALLOW. Using RELENG_3 the tape always rewinds on the "DUMP: Closing /dev/nrsa0" message which appears on the console. Note that a person running X-windows would not see the error messages.
