Exception : Reported error: End code 5.0 when running with eva = pdflabel

I am trying to generate aa>bb~ from electron or muon PDF, that is with
     3 = lpp1 ! beam 1 type
     -3 = lpp2 ! beam 2 type
When using
     eva = pdlabel ! PDF set
I get Exception : Reported error: End code 5.0
using
     iww = pdlabel ! PDF set
it works. Is this a case in which eva is not supposed to be used? On what cases can eva be used?
