ORA-00600: internal error code, arguments: [kaf lob buffer overwrite], [2192], [466], [], [], [], [], [], [], [], [], []
00600. 00000 -  "internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s]"
*Cause:    This is the generic internal error number for Oracle program
           exceptions. It indicates that a process has encountered a low-level,
           unexpected condition. The first argument is the internal message
           number. This argument and the database version number are critical in
           identifying the root cause and the potential impact to your system.*
