The ITMX cps had started glitching this week, I tried reseating the cards to fix the glitching, but I guess I forgot to reconnect one of the sensors. The St1 h1 sensor is railed, so the watchdogs nominally can't be reset. I've temporarily bypass the st1 cps in the wd (via an epics variable that raises saturation threshold above the adc range), but the bypass will reset, eventually. I'll reconnect the st1 h1 sensor tomorrow morning.
