    During SDUMP processing, module IAXCG was called to capture
    address space storage. The current VSA being processed was
    shared high virtual. The segment table does not exist within
    the address space region 3rd table but rather the common region
    3rd table.  The page table does not exist for the VSA and the
    segment not available indicator was not set.
    This also resulted in no PTE or PFTE address being available,
    resulting in and ABEND0C4 when trying to reference this VSA.
    

Problem conclusion

  • The code is changed so that the proper page and segment tables
    are used for addressing the high virtual shared storage
    during IAXCG processing
