ORA-00600: internal error code, arguments: [krbmror_sameline_2]

Hi,

 We are using OEM Grid Control to run RMAN backup job that directly backs up to the tape.

We do not have "SET ECHO ON" in the RMAN script, but occasionally the script run throws "ORA-00600: internal error code, arguments: [krbmror_sameline_2]" error.

Found the below in the Oracle support site:

 Bug 10098253 - ORA-600 [krbmror_sameline_2] from RMAN "set echo on" (Doc ID 10098253.8)

But it says the reason for this ORA-600 is only if "set echo on" is used in RMAN script which we don't.

Anyone had similar experience?

The script in use:

SET BACKUP FILES TO NOTACCESSIBLE;

backup device type sbt tag '%TAG' archivelog all not backed up; backup device type disk tag '%TAG' archivelog all not backed up; delete noprompt archivelog until time 'sysdate - 5' backed up 1 times to device type sbt; resync catalog ;
