Error description

  • When a shared memory corruption is reported:
    
      Assert Failed: Memory block header corruption detected in
    mt_shm_malloc_segid 6
      IBM Informix Dynamic Server Version 11.70.FC5
       Who: Session(34, user@server, 31703, 0x10f739998)
             Thread(102, sqlexec, 10f6fb418, 29)
             File: mtshpool.c Line: 1912
       Results: @^_^Y^T217
       Action: Please notify IBM Informix Technical Support.
      stack trace for pid 31578 written to
    /opt/informix/11.70.FC7N/tmp/af.44e7b75
       See Also: /opt/informix/11.70.FC7N/tmp/af.44e7b75
      Memory block header corruption detected in mt_shm_malloc_segid
    6
    
    you can see that the expected string after "Results: " is
    garbage (or in other cases it might be empty).
    
    This has no functional impact and having or not having this
    string is not related to the cause of the AF. However, for the
    internal investigation of support to know the string might be
    helpful to gain further insights what went wrong internally.
