Error description

  • ABEND378 occurred in IGVVSERR, during freeing of an MVS dataset.
    This storage release was triggered by a TLS handshake failure
    for an FTP connection..  The release of storage obtained in key
    0 while running in key 8 is what caused the abend378.
    .
    VERIFICATION STEPS:
    1) Obtain a dump of the S378 abend.  IP VERBX LEDATA
    'NTHREADS(*)' will show a calling sequence similar to:
    Traceback:
      DSA      Entry       E  Offset
    
      1        OSBCLOSE    -09AE074A
      2        osclose     +000002A0
      3        cp39        +000002E4
      4        __tcloseall +00000566
      5        _cTterm     +000003AA
      6        CEEOTERM    +0000106C
      7        CEEZRET     +0000033A
      8        CEEBBEXT    -0921F316
    .
    2) If AT-TLS is being used, the SYSOMVS ctrace might show an
    error on a SIOCTTLSCTL ioctl.  The errno jr will be 77B70025

    * PROBLEM DESCRIPTION: When using GET subcommand to download   *
    *                      an MVS data set and TLS or AT-TLS       *
    *                      policy is used for the data connection, *

    *                      FTP server exits.                       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When FTP server handles the GET subcommand, firstly it opens
    the data set using CSM storage key 0 and then before data is
    transferred, it tries to do data connection negotiation for TLS
    or AT-TLS. If the negotiation fails, currently the FTP server
    does not close the data set before exiting. This would leave the
    data set allocated, so Language Environment would need to clean
    it up, but Language Environment does not use key 0 to release
    the CSM storage, which causes the ABEND 378 with RC 14 occurs
    when the FTP server ends. FTP server should close the data set
    after the data connection fails.
