Corrupted file for kaons

[tvami]

When running on the kaons I get a segfault (see below).

I think we should just deleted this file

 /fs/ddn/sdf/group/ldmx/data/mc24/v14-8gev/8.0GeV/v3.3.3_kaon-batch1/mc_v14-8gev-8.0GeV-1e-ecal_photonuclear_kaon_run1391_t1709367110.root 

@bryngemark can you please do that?

hi @tvami, i can delete it. is this the only corrupted file in the kaon dataset?

[tvami]

Yes, I should rename the issue to remove the plural, I was ready to have a longer list, but this seems to be the only one. Thanks for deleting it @bryngemark !

[tvami]

I actually have a bigger picture question too: when LDCS is used and you have several files as input, but one of them is corrupted, how is that handled? Because for me I got this segfault and my other dozens of files were ignored since the final output file was bad.

[tvami]

File is deleted now

This happens with LDCS too. Fixing it such that we can deal gracefully with corrupted files would help a lot, thanks for working on that.
