The data from the Licor at 16 meters went bad on Oct 2, while our system was not reachable over the network.

The ldiag averages went from the typical 248-255 range to around 216.

This CWEX11 logbook entry has some information about the licor diagnostic value:
This morning at around 10:40 MDT, I logged in and looked at the high rate data with rserial. (The 16 meter licor is serial port 11) The diagnostic value is 215 = 11010111 binary. Bit 5 is 0 indicating the PLL is not OK.
...
The \t are tabs between the values. 255 is the ldiag value, indicating a high AGC value, but all other
diagnostic bits are OK. The second and fourth values in a message are the raw values for co2 and h2o, which look crazy, and the calibrated values are "Overflow". This will probably clear up when things dry out.
