You don't have enough energy, and EvtGen is not letting your pbarpSystem decay:

This top particle is pbarpSystem 4.410 (10.365,0.000,-0.000,9.380)
pbarpSystem -> D'_s1+ D_s- 2.525 (2.525,0.000,0.000,0.000) 3; 1.968 (1.968,0.000,0.000,0.000) 



With your momentum you have sqrt(s) = 4.410, but the mass sum of D'_s and D_s is 2.525+1.968 = 4.493. This is the reason why you have such error messages from evtgen.
You should increase your momentum.
