Error description

  • Rational Developer for System z 9.5.0 systems get a wide variety
    of symptoms due to 6 byte storage overlay in the CSA or ECSA
    
    Symptoms include many different problems.  S0C4 abends, Data
    sets not found, HFSs not mounted, OMVS broken, overlay in the
    CSA of the CATALOG address space. It all depends on which system
    service gets hit.
    
    Problems have been observed on z/OS 1.13, z/OS 2.1 and z/OS 2.2.
    Only RDz 9.5.0 is affected by this defect.
    
    To match this defect:
    - The overlay is x'000000' in the first 6 bytes of the damaged
      area.
    - The owning job of the preceding area is RSEDx where 'RSED' is
      the RDz started task jobname and 'x' is a digit.
    - The control block, which lives in COMMON STORAGE, is RDz
      storage with a length of x'170'. The return address
      listed as requesting that storage is "bin/fekfrmsg"
      IP WHERE req_addr ASID(X'0123') shows e.g.
       | /products/rdz950/bin/fekfrmsg    |
