This morning, S15's EC150 stopped reporting. It appears to be associated with a ddn/dup at 1451 UTC. (There are several data files around this time. Data are in the file starting 1438 and not in the file starting 1451.) I've just tried eio 5 0/1 and failed to revive it. It also doesn't respond to <cr> to get a prompt. However, the station's Iload was constant during this period (and similar to the day before), which makes you think that the sensor is still trying to function.
FIXED: Somehow emode on 5 was back to 232 (even though it <should> have been set by the script pre_dsm.sh). I just manually entered: emode 5 422 and data started flowing.
