Error description

  • There is a very small timing window near the end of backup
    database processing in which a second backup database process
    can start. If this should occur it is possible for the second of
    the two processes to end up with an invalid pointer at startup
    resulting in a segmentation fault in IcInsertCtlItem.
    The following is the stack trace at the time of a failure:
    pthdb_session.c, 833: 0 PTHDB_INTERNAL (internal error)
    pthreaded.c, 1953: PTHDB_INTERNAL (internal error)

    Tivoli Storage Manager Versions Affected: 6.1 and 6.2
    Initial Impact: Medium

Local fix

  • Ensure scheduled database backups are scheduled to start far
    enough apart to avoid any overlap.
