@sawenzel @jackal1-66 do you understand the errors about

545/549 Test #506: o2sim_checksimkinematics_G3 ..........................................................Subprocess aborted***Exception:   1.48 sec

which are starting to appear since around yesterday?

Do you also understand the other one about the missing Pythia8.h?

Does not touch anything in production just a test (which works correctly). Merging.

I'm running a test on o2sim_checksimkinematics_G3. I see that it fails on the TPCtracks when checking for the trackref size, but I want to see if this fails also locally (and understand why the mcreader it's getting a 0). Regarding the Pythia8 issue instead I have no clue right now. The only recent modification in GeneratorPythia8.h is unrelated to this. Were there some updates on the building machine side instead? Locally on my slc9 pc I don't get this issue.

After talking to @sawenzel I opened #13721 to fix the issue with the missing Pythia8 header. Still investigating on the o2sim_checksimkinematics_G3 problem instead.
