Error description

• ABN=0C4-00000011,U=,C=R3600.800.SSSC-CSQ3CL0X,M=CSQ3CL0X,
  LOC=CSQ3EPX.CSQ3CL0X+0000011C
  
  We receive an ABEND0C4 in CSQ3CL0X at offset x'11C'.
  The 0C4-11 occurred on a LOAD 584021F8, because the
  storage where R2 is pointing to (21E4E000) is not available.
  The SYSTRACE shows a PR from CSQ3EC0X prior to the Abend
  
  GBDDRUCF is going through SSI EOT processing at the same time as
  XGDAMSTR is going through EOM processing. The procesing in
  GBDDRUCF has already loaded the address of the SCOM from
  ERLYSCOM, but the EOM processing has resulted in the SCOM
  being released. This has caused the 0C4.

  ****************************************************************
  An address space which has connected to MQ is going through
  SSI EOT processing in CSQ3CL0X at the same time that the queue
  manager is going through EOM processing in CSQ3EC0X.
  CSQ3CL0X has determined that the SCOM is still available
  (ERLYSCOM is not zero) but then loses control. In the meantime
  CSQ3EC0X calls procedure CSQ3EC04 to free the SCOM. When
  the CSQ3CL0X task resumes it tries to address a field in the
  SCOM, but since it has been freed up then an 0C4 abend occurs.
  

Problem conclusion

• CSQ3CL0X has been changed so that if the SCOM is freed up then
  ESTAE processing will handle the condition.
