Can not write output of integrated process
Dear MG Team,
I was trying to study a fololowing process at the NLO level:
generate p p > vl vl~ a j j QCD=0 QED=5 [QCD]
with MG5_v.2.6.4.
The integration completed successfully.
While generating the output folder (by 'output -f' command), the following error message is coming:
INFO: Generating virtual matrix elements using MadLoop:
INFO: Generating virtual matrix element with MadLoop for process: b~ b~ > vt vt~ a b~ b~ QCD=0 QED<=5 [ all = QCD ] (492 / 492)
WARNING: Some loop diagrams contributing to this process are discarded because they are not pure (QCD)-perturbation.
Make sure you did not want to include them.
INFO: Generated 492 subprocesses with 390192 real emission diagrams, 28512 born diagrams and 219456 virtual diagrams

MadGraph5Error : Failed to clean correctly PROCNLO_
[Errno 12] Cannot allocate memory
I have more than 15 Gbytes free on the disk. Why do I get such error? How to solve it?
gfotran is in place
gfortran -v
