Hi,

Well this does not make sense. 
in the log file, I do not see anything wrong (no crash/...)
Additionally, the log file endswith a "ls" command
which shows that the file results.dat exists.

While madgraph crashes because this log file does not exists...
So this is likely a filesystem syncronization issue (or transfer of file).

Not sure what I can do here to help you without knowing how your cluster is setup.

Cheers,

Olivier
