Thanks Maurik,
I tried on the scrubbed file and got the same result:

It would be interesting to see if the “scrubbed file” (/work/hallb/hps/maurik/hps_005754_scrubbed.evio.4) can be processed without problems.

Then the DQM job ran on the empty LCIO file (the "0 events" message) and failed (NullPointerException in SvtMonitoring.endOfData()) because there's some DQM drivers that don't cope well with empty histograms.
