19:18 UT Reboot ROACHes to clear fault light and test whether large delays are still present. They were power-cycled and reloaded.
19:24 UT Started roachcal.scd to take packet capture data for checking delays. Still bad!
03:41 UT Found a potential problem DELAYCAL_END.ctl, so took another two sets of data. Still bad!
04:14 UT Started another set of data. After studying schedule.py, another problem was found. DELAYCAL_END command has to have CIEL-2 as second value on the line, otherwise source id is set to None!
