Thanks for the brainstorming, Flemming...

I have only on a couple occasions re-run a job myself. Neither time was the
problematic job problematic when I processed it. To make things more
confusing, jobs that ran later in FastOffline for the same run also had
issues. See this list of jobs for run 25149018 sorted by their job start time
(EDT) on Tuesday, where the jobs with an asterisk * showed the issue:

> - What triggers do fast offline use?

No selection of triggers. Everything in the DAQ files, but only for certain
DAQ file streams.

> - fastoffline do analyze both physics and adc_physics , yes?

Yes, though st_physics_adc has offline TPC cluster-finding turned on. I can't
remember whether I fully determined that you no longer need this for the TPC
QA you and Isaac set up, but at first I found we did need it.

Thanks,
