    12547 ISTORCDI received control to initialize the newly created
    data space. It tried to store the information the data space
    address zero. This caused the abend0c4 in ISTORCDI.
    12918 When F NET,CSDUMP,MESSAGE=,RNICTRLE= is issued, a 0C4 in
    subroutine PROCRNIC of ISTRACSW can occur
    
    13238 The Enterprise Extender (EE) T1 or TL timers were canceled
    before the both the EE PU and PC PABs were quiesced and this
    allowed another EE timer to be set and the Abend 0C4 condition
    during VTAM termination.
    13339 An abend0c4 occurred  during a SNA  PU deactivation. The
    abend occurred during a destructive run where VTAM was shut down
    and the RDTE of the higher level node  of the PU was not
    available. During deactivation of resources, ISTEDCVP  issues a
    GETRDTE higher level macro, but did not check for the return
    code to verify if a valid RDTE was returned. In this case, the
    return code was no zero and an attempt was made to reference a
    null pointer. The GETRDTE macro is supposed to return with a
    pointer to the higher level node if it exists.
    13400 1. SMCST_TASK_BITMAP(0:4096) BIT(8) have only 32K bits. We
    use low order two bytes of TCB address.  It needs 64K bits to
    represent it.   2. IVTSMCST has only 32K bits for possible TCB
    addresses. There was not enough bits  for all TCB addresses.
    This caused the abend0c4 in ISTAPCTT.
    13417 A timing window exists where TCP/IP was terminating an
    SMC-R link at the same time a VTAM timer (TQE) popped to timeout
    the link.   The fact both signals were being processed at
    approximately the same time caused VTAM to attempt to free the
    SRQP_TQE twice,resulting in the ABEND0A9.
    
    13593 When activating a dynamic TRLE for an OSM device, we get a
    0C4 at IUTLLCRM +C0C.
    14053 Timing conditions when collecting diagnostic dump
    information for the RoCE Express feature can cause the dump
    information to be unusable.
    13370 Some records in a group of VIT records tracing SMC-R
    operations are not being generated correctly
    14080 Modify message text for ISTM013I and ISTM014E.
    13282 Problem with RMB buffer expansion while the LG is not
    active and there are significant timing windows with the
    registration with all links in the associated LG (SMC-R link
    group). This can cause issues with a connection not being able
    to fail to an alternate link if the TCP connection is required
    to fail-over to an alternate link.
    

Problem conclusion

  • 12547 VTAM is changed to obtain the data space starting at the
    address X'1000'.
    12918 When the message that triggers a CSDUMP is not running in
    VTAM's address space, issue message IST2400I and do not take the
    dump. 13238 Changed ISTAUCDL to force the PU and PC PAB to be
    quiesced prior to canceling the T1 and TL timers
    
    13339 ISTDECVP has been amended to check for return code after
    the GETRDTE macro is issued.
    13400 IVTSMCST has been changed to have 64K bits
    SMCST_TASK_BITMAP.
    13417  When the SRN_TQE was freed by the first process, the
    field pointing to the TQE was not cleared.  This allowed for the
    second process to free the TQE. Code changes have been made to
    clear the SRN_TQE field when the storage is being freed.
    13593 Ensure when any failure to allocate a dynamic TRLE occurs,
    no further processing of the signal that caused the allocation
    failure is attempted. 
    14053 VTAM will delay up to 15 seconds after requesting a
    diagnostic dump, pending notification from PCIe services that
    the dump has completed. If the dump doesn't complete in 15
    seconds, VTAM continues processing
    13370 Corrected VIT record invocation to pass the correct source
    address for the entire group of VIT records, not just the last
    record
    14080 Made the correction to the following 2 messages for the
    ZOSMIGV2R1_CS_GATEWAY migration check. ISTM013I  GATEWAY
    statement is not in use on this system.  ISTM014E GATEWAY
    tatements are in use on this system during this IPL. 2 Change
    EZBSRUTL to register any expansions during first contact
    activation after the alternate link is activated (if there is an
    alternate link). Also had to make changes to ISTSRIS8 and
    ISTSRIRU to correctly register these resources
