Question Problem when use command "/process/inactivate msc" with QGSP

Hi all,
Now i use Geant4.8.1 and QGSP 3.0. I 'm simulating the GlueX detector. 
It composes of sub-detectors such as BCAL, FCAL, CDC. Then i have to 
study the effect of msc on the invariant mass reconstruction of X+ in the 
gammaP->X+n->Pi+Pi+Pi-n reaction. The beam of gamma has 9 GeV of energy. 
The event generator results in three Pi's that are used as input to my 
PrimaryGeneratorAction.
1.I design to use the QGSP as my PhysicsList. Am i correct? 
  Are there any PhysicsLists more apppropiate? 
2.When i use the command "/process/inactivate msc" to turn off msc. 
  The G4 works properly but at the end of running there are messages
     
   G4ProcessManager::GetAttribute():particle[e-]
         index out of range
         #process[4] index[-1]

  There are no messages when inactivate muBrems. Are they the warning or 
  error messages? The results from running still correct?    
3.Do you have any suggestions or methods to analyze the effect of msc?
Thanks a lot,
Chakri.
