This is the first unexpected restart of either frame writer following the DAQ reconfiguration made several weeks ago. This restart is likely attributed to LDAS starting the disk archiver at that time, which intensively scanned the frame writers' disk systems. We would expect h1fw1 to be more susceptible to crashing when this is happening since it is writing the larger commissioning frame.
