Yes, exactly... but this was in the middle of the night, after I'd
already been commanding the spectrographs for several hours.  It
seems like something interrupted communications but I couldn't tell
anything obvious according to the SOP output.  Nor did I try a
grabInst -drop/grabInst -handlers etc.  I just kept requesting the
postCal until it took.

Craig pointed out, which I didn't know, that SoS mirrors what's on
host2 (probably something like rsync running every so often as a cron
job).  Well, I shouldn't say I didn't know, but rather that I figured
SoS would purge the data it's already reduced once finished.  I
didn't make the connection last night 1) not having seen this error
message before and 2) noting that the /data partition on host2 was at
something like only 81% capacity, though of course it has more disk
space.  Elena pointed out all the OK_TO_REMOVEs on host2, and in
retrospect that's what we should have done.  Lesson learned!
