When I checked the data retransmission status for GWFs during the planned power outage, I unexpectedly found two daqd hang-ups on k1fw0 which were not related to the power outage itself.
As a result of these hang-ups, GWF files on k1nds0 were missed in during segments which corresponds to 2 full and science GWF files per each segment.
[1443281408, 1443281472)
[1443290656, 1443290720)

Data in Kashiwa doesn't seem to be affected because a primary data source is now set as k1fw1.
