PROBLEM DESCRIPTION:                                                      
CA 7 may loop when an LQ,LIST=JCL,JOB=* command is issued. This can       
occur when JCL is moving through the CA 7 queues while jobs               
are being processed.  CA 7 is unable to get the next JCL                  
segment for display but keeps trying to do so rather than                 
terminate.                                                                
                                                                          
SYMPTOMS:

errors in the CA 7 JES2 Joblog.  It is possible this could                
overload the JES2 spool.                                                  
                                                                          
IMPACT:                                                                   
CA 7 will need to be re-cycled.  JES2 Spool may be overloaded             
with messages.                                                            
                                                                          
CIRCUMVENTION:                                                            
Don't issue LQ,LIST=JCL,JOB=*
