106	BNC Client v 2.12.6 latency metrics stop recording in the log at beginning of UTC week	edanastasio	stuerze	"Hello,

We are running the BNC Client to collect latency metrics and create 1s Rinex2 files from our streaming stations across New Zealand. We manage about 50 streaming sites with one instance of the BNC client.

We have upgraded to the latest BNC version (2.12.6) last week on 2018/05/16.

BNC Client stopped logging metrics at the beginning of the midnight of UTC day 2018- 05-20. The latency records restarted normally after a restart of the BNC Client.

I have enclosed the configuration file we use with the BNC Client (only username and password are changed in there) and the BNC log file for the day that had the latency metrics dropping off.

We run BNC Client on: 
Linux 3.10.0-862.2.3.el7.x86_64 x86_64 x86_64 x86_64 GNU/Linux

with the following command:

{{{
/usr/local/bin/bnc -nw --conf /work/bnc/conf/BNC.ini
}}}

I know that our colleagues at Geoscience Australia are having the same problem, and they experienced the same behavior at the beginning of each UTC week.

As a side note (I'm not convinced these two things are related) we noticed that, differently from the bnc 2.12.6 logs of previous days, the log dated 2018-05-20 is showing a message about some outdated ephemeris of the BeiDou constellation.
There are lots of records similar to that in previous logs, but they were related to Galileo and QZSS constellations only. Beidou entrances are only showing when the latency records stopped on 2018/05/20.
