Error description

• INVALID ADDRESSING MODE BIT SET BY OBJECT ANALYSIS CAUSES MEDIA
  MANAGER TO ABNORMALLY TERMINATE WITH ABEND0C4 / ABEND0C1
  
  Invalid addressing mode bit set by Object Analysis causes Media
  Manager to abnormally terminate with ABEND0C4 / ABEND0C1
  
  The AMODE problem is caused by a series of LLGTR instructions
  (load logical thirty one bits) at the beginning of the OMEGAMON
  
  At the point in time of the S0C4, R14=010FDEFA and the PSW at
  time of error is 070C3000 000FDEFA.  R14 is used within a BSM
  instruction and therefore switches the AMODE of the PSW to
  AMODE24 thus causing the S0C4.  R12 at the point in time of the
  S0C4 ABEND points to the entry point of DSNB5UTX (R12=1CEDC5C8)
  and therefore the critical BSM instruction is executed out of
  DSNB5UTX. DSNB5UTX is at maintenance level UQ75848 (DSNB5UTX
  04/09/03 UQ75848) and DSNB5UTX contains a return instruction via
  PSARET (PSA+37A, PSARET points to a BSM R0,R14).
  
  Modules hit: KO2EOJSA and KO2EIX12, KO2EIX1S, KO2EIX1A
  

Local fix

• Turn off Object Analysis untill an APAR fix is available.
