    - In the same second, the following errors are reported in the
      dsmerror.log file on the client:
       ANS0361I DIAG: ..\..\common\cu\cucommon.cpp(1509):
        cuGetAuthResultEx(): Error -50 receiving AuthResultEx
       ANS0361I DIAG: ..\..\common\winnt\psthread.cpp( 554):
        Destroy mutex failed; reason 6.
       ANS1017E Session rejected: TCP/IP connection failure.
       ANS0361I DIAG: ..\..\common\cu\cucommon.cpp(1509):

        Destroy mutex failed; reason 6.
       ANS1017E Session rejected: TCP/IP connection failure.
    - That will most probably happen when saving large filesystems
    with millions of files.
