Error description

  • If an API lanfree session is canceled by a user, or for a
    pre-emption, the application using the API may hang or see a
    crash of the tsmapi64.dll. This happens when the API main thread
    completes its work for the loss of the session before the the
    function thread.
    .
    This affects 7.1 and earlier code and can affect any application
    using the windows 64bit API for lanfree backups and sharedmem
    for the commethod. For example the windows eventlog can show the
    below for TDP for Oracle.
    .
    Faulting application name: ORACLE.EXE, version: 11.2.0.3, time
    stamp:
    0x52773721
    Faulting module name: tsmapi64.dll_unloaded, version: 0.0.0.0,
    time
    stamp: 0x54112bfd
    Exception code: 0xc0000005
    Fault offset: 0x000007fee64b5628
    Faulting process id: 0x3c51c
    Faulting application start time: 0x01d01433156acafb
    Faulting application path:
    c:\oracle\product\11.2.0\dbhome_1\bin\ORACLE.EXE
    Faulting module path: tsmapi64.dll
    Report Id: f3024399-8090-11e4-a330-90e2ba09c08c
    .
    The client error log may show a -72 error that a session failed,
    and the backup will show as completed
    .
    Initial Impact: low
    

Local fix

  • avoiding preventable canceled session such as pre-emtions can
    minimize the occurrences, or use TCPIP for the LANFREECOMMMETHOD
