As an intermediate solution, what we can do is to not consider such problematic PF candidates in isolation sum of photons. This way we won't have nan isolation for photons...
right so now I checked that the issue also happen (rarely though) in data (checked in 2022C). I don't quite like photon's charged isolation being `-nan`; so I prepared a...
okay after a few more checks, the real issue seem to here: https://github.com/cms-sw/cmssw/blob/6d2f66057131baacc2fcbdd203588c41c885b42c/RecoParticleFlow/PFProducer/src/PFCandConnector.cc#L159-L161 before doing that division, we should check that the divisor is `>0` with this patch, the issue...
> wouldn't it be enough checking that `momentumPrim.E() > 0` ? Hello @perrotta, you are right; The divisor is just `momentumPrim.E()`, so checking that to be `>0` is sufficient to...
> I don't really understand how the energy can be zero here, is the p4 also fully zero? yeah.. no idea why `momentumPrim.E()` is zero, actually `px`, `py`, `pz` are...

It might be useful to keep the `LogWarning` messages in `TrackingTools/TrajectoryState/src/BasicTrajectoryState.cc`, as they are helpful to discover other bugs while code-development, debugging crashes that shows up, etc. With this PR...
Hello Marino, yes, you can remove hltEgammaGsfTracks from the suppressWarning list. We also plan to work on the remaining error messages, but that's a bit more long-term thing. Thanks, Swagata.
Three examples are pasted below: ``` A fatal system signal has occurred: segmentation violation The following is the call stack containing the origin of the signal. Sat Jun 18 18:31:53...
Experts are working on providing a recipe to reproduce the crashes offline. (tagging @mzarucki and @fwyzard ) Once that is available, that can be posted here so that tracker DPG...
