Summary

0000423: Corrupted EVIO files?

Description

Some fraction of data files have an issue that part way in, the EVIO library gets confused. Initial debugging looks like it is interpreting a word from the middle of a data block as a length word for the next EVIO event. It's unclear if this is due to corruption of the file or a bug in the library reading it. Regardless, the DAQ plugin should try and work around this error.

Richard Jones reported getting the error at around event 1000 of hd_rawdata_001411_000.evio.
