Thanks a lot Olivier!
The patch solved the problem.

Best regards,

Thanks Olivier Mattelaer, that solved my question.

Dear Won Jun, dear Olivier,

thanks for opening up this thread. I had the same problem. Using the patch/downloading the newest version still did not quite resolve the issue, but setting in the mg5_configuration file the machine as a single-core helped to resolve the problem. Just wanted to write that up, in case somebody still is not able to run MadGraph v2.9.14.
