Mmm. So this looks like you reduced the problem but didn't elimiate it?
It might be that running in this minbias mode with this tune, 
herwig+jimmy actually (rarely?) exceeds 10000 particles? If the fortran 
herwig and jimmy is compiled without bounds checks this could have 
unpredictable results.

(of course good fortran should protect against such things and herwig 
and jimmy may do but I am not 100% sure).

If I had a working set up now with herwig and jimmy compiled myself, I 
would insert write statements in to see what NHEP and MAXER are at the 
end of each event...

Cheers,
Jon
