Issue:
Applied all ptfs available from Jan. 1 2018 to July 3 2018. After IPL to use new Top Secret maint, I am getting an 0C4 in sshd. I
Cause:
A storage overlay of 4 bytes of zeros can occur when a USS/OMVS       
thread enters fork or spawn processing.  This overlay can cause       
unpredictable results, including IBM message BPXP005I with return     
code x'00000070' and abend code S0E06.  This only occurs if the       
the OMVS user does not have any connected groups assigned.            
                                                                      
SYMPTOMS:                                                             
BPXP005I A FORK OR SPAWN ERROR WAS ENCOUNTERED. RETURN CODE 00000070  
REASON CODE 0BFC0000

IMPACT:                                                               
Unpredictable depending on the content of the storage that is         
overlayed.  USS processes may abend abnormally.                       
                                                                      
CIRCUMVENTION:                                                        
Insure all OMVS users have a GROUP definition that matches the        
default group assigned to the user.
