[Rivet] Jimmy stops with CODE 300

[Jonathan Butterworth]

I misremembered the name, it's NMXHEP, which dimensions the particle 
array in the HEPEVT common.

As you are using 6510 it's 4000, if you use 6510.2 it's 10000.

The recommended value is 10000 for LHC running. I think this may be your 
problem

- if your local jimmy build has 10000 then there is an incompatibility. 
It will depend where you are picking the herwig include file from when 
you build jimmy.

- even if they are both consistent and 4000 its possible there is an 
nchecked overflow somewhere if a rare events exceeds 4000 particles, 
though I would hope they are all checked!

Cheers,
Jon
