ttZ@NLO aMCatNLOError : An error occurred during the collection of results.

Asked by Josh McFayden

Hi all,

I've run into a problem running ttbar+Z production at NLO. Maybe I'm just doing something stupid and I'm sure this worked in the past but I've run out of ideas.

I get this error:

ERROR: not all jobs terminated correctly

INFO: Return code of the event collection: None
INFO: Output of the event collection:

8 jobs did not terminate correctly:

The results are probably not correct. Please check the relevant log files corresponding to the above jobs for more information.

Ciao Josh,
sorry for the delayed answer...
we are looking into this problem, but it looks like we are not able to reproduce it on our machines...
Is it still there in 2.2.2?
Then, can you try to run the code in aMC@NLO mode (not NLO fixed order as it looks like from your log) and see if you get a number?

I will look into the code to see what the NaN's can be related to and let you know asap.

Cheers,

Marco

Hi Marco,

Even I cannot seem to reproduce the problem now... it seems to be running just fine and I have no idea what changed.
Very sorry for wasting you time.

Cheers,

Josh.
