  ****************************************************************
  When the WLM address space goes to EOM, an 0C4 abend may occur
  during the EOM processing. This is due to a timing window where
  one of the DB2 control blocks may already be freed but it is
  still referenced in the EOM processing without checking whether
  the pointer points to the control block is zero or not. This
  would result in the 0C4 abend.
  

Problem conclusion

• The code in the stored procedure/UDF EOM processing has
  been modified to check the validity of the pointer before
  referencing the fields in the control block.
