SGP/SONDE - Data missing from sounding

It appears that the collection of the raw data file was interupted by the
SDS.  The following message appears in the raw file
(sonde-hills10003161901.rawraw):

  12  0     4.8    4384    589.3  -11.0  87  -12.7  274  12.8 110001110110

#Collection process shut down by SIGTERM

Another raw file (sonde-hills10003162145.raw) follows with:

~LL?
  73 30     4.7   22154     37.9  -63.4   1  -93.3  250  13.2 110001110110

I don't understand the cause of this problem, but am confident that it
is not instrument related.  These files were merged on ingest.
