Attached 4 CSAT3 sonics to cosmos. Each sonic is Y'd into 4 serial ports,
in order to simulate 16 sonics into one adam. The sonics are configured
for 20hz, (parameter Ac).

cos000610.235245: started test
cos000611.000000 OK
cos000611.080000 OK
cos000611.160000 died at 22:07 (16:07 MDT)
cos000611.220818 restarted itself, but ironics did not come up
cos000612.032846 did an MXRESET. ok
cos000612.080000 ran until 15:57 (09:57 MDT)
So, there are 2 unexplained adam crashes. The other adams kept
running (though they only had 1 1hz analog port enabled).
A data_dump of channel 0 showed no problems before the crash:
data_dump -f cos000612.080000 -c 0 -A
syslog also showed no errors, except for ingest timeouts after adam crashes.
Covars look good during this time. In 23 hours of data from Jun 10 2352 to
Jun 11, 22:07 GMT the results are identical for the four ports connected
to a sonic.
The only differences seen are when a sample is put into a
different 5 minute average. Here are some u averages:

[1,] 6001 6000 6001 6000
[2,] 6000 6001 6000 6001
On two channels, 6001 samples are summed the first average and 6000 in
the second average, and vice-versa for the other two channels.
