MadGraph getting into error after producing some runs

[José David Ruiz]

I have produced a couple of runs of MadGraph+Pythia8+Delphes without any problems for a SM process. However when I reached run 5 MadGraph is going to error. I attach the log file, and here the output in command line:

joser@as-physr200113s:~/Pheno_Studies/MG5_aMC_v2_6_1/qcdzwjjjj_5f_LO$ ./bin/generate_events -f

Hi Jose,

This should be a filesystem issue.
In your system (and a some point) your IO is too slow compare to the speed to which some command are executed.
So looks like that the file moffset.dat which is read by our fortran executable to ensure to have independent running sequence is not created fastly enough to be readable
when requested.

Like this I do not see any easy solution.
(The only solution that I can see is to change the method to read that information from a hardcoded file to a stdin input and/or argument as done for some other paramaters)

Cheers,

Olivier
