I hope someone notice this currently looking for fix for MCH0601 for our P7 machine V7R3 sharing screenshot below problem.

Message ID . . . . . . :   MCH0601       Severity . . . . . . . :   40        
Message type . . . . . :   Escape                                             
Date sent  . . . . . . :   05/28/25      Time sent  . . . . . . :   14:20:24  
Message . . . . :   Space offset X'00000000' or X'000000000020A0AA' is outside
  current limit for object PS401T    SIGOPER   597669.                        
Cause . . . . . :   A program tried to set a space pointer, tried to use      
  storage outside a space, or tried to use an unallocated page in teraspace.  
  The space class is X'07'. The space class designates the type of space:     
    00-primary associated space (includes space objects).                     
    01-secondary associated space 0.                                          
    02-implicit process space for automatic storage.                          
    03-implicit process space for static storage in activation group mark     
  X'0000000000000000'.                                                        
    04-implicit process space for heap identifier X'00000000' in activation   
  group mark X'0000000000000000'.                                             
 05-constant space.                                                      
  06-space for handle-based heap identifier X'00000000'.                  
  07-teraspace offset X'000000000020A0AA'.                                
  08-teraspace for System i5 PASE memory address X'000000000020A0AA'.     
  Offset X'00000000' only applies to storage outside teraspace.           
X'8000000000000000000000000020A0AA' is a pointer to the teraspace page or 
the start of the implicit process space for the allocation.
