I noticed, via my performance tools, that one of my QZDASOINIT jobs, was taking 30% of CPU, for a 12 1/2 hour period.
From the performance data/graphs, the process started 2/6 15:00, ended 2/7 3:16, due to an error.
Only thing in the QZDASOINIT joblog is CPIAD07 Host server error occurred with reason code 7.   
How can I find what job requested the use of the  QZDASOINIT job?       
Message ID . . . . . . :   CPIAD07

    1 -- Resolve to the host server daemon program failed.                     
    2 -- Retrieval of the host server daemon program lock failed.              
    3 -- Submit job to start the host server daemon job failed.                
    4 -- Allocation of the host server daemon program failed.                  
    5 -- Starting of the host server job failed.                               
    6 -- Ending of the host server daemon job failed.                          
    7 -- Activation of the host server job failed.                             
    8 -- Processing of exchange random seed request failed.                    
    9 -- Processing of start server request failed. 
   10 -- Reallocation of server buffer failed.                            
    11 -- Deallocation of the host server daemon program failed.           
    12 -- Resolve to the server specific user space failed.                
    13 -- Resolve to the trace buffer user space failed.                   
    14 -- Resolve to the trace buffer user queue failed.                   
    15 -- Read operation from the server specific user space failed.       
    16 -- Read operation from the trace buffer user space failed.          
    17 -- Write to server specific user space failed.                      
    18 -- Write to server trace buffer space failed.                       
    19 -- Enqueue operation to the trace buffer user queue failed.         
    99 -- Unknown processing error occurred.                               
Recovery  . . . :   Determine the cause of the error; if necessary, correct
  the error and retry the request.
