Greetings and Goodevening,                                                                                                                                           
                                                                                                                                                                     
The ppe.poe 3.2.0.0 is base level software which has been

More recent upgrades i.e. after the change freeze in blackforest                                                                                                     
are possibly got guided by security upgrade of the base O/S and                                                                                                      
hence the related dependence that followed. But earlier upgrades                                                                                                     
might have had some bearing on specific problem fixes. As a policy                                                                                                   
we can not keep our system too downlevel from the reccommended level                                                                                                 
by IBM as we may loose support.                                                                                                                                      
                                                                                                                                                                     
Every fix solves some problems and as you know often creates new                                                                                                     
ones! Most of the problems that a upgrade could potentially solve                                                                                                    
might not have been encountered here but is carefully been documented
