[Frédéric LOUI <>]

Hi Marcos,

I hope you are doing well.
I’m doing some forensics on RIO0001.

As from now, I see that there is a problem related to the interface between 
the controls plane (freertr) and the dataplane.

Indeed for unknown reasons bf_forwarder.py is initiating a GRPC session and 
immediately quit.
This is a weird observation and this is the first time I see this. At least 
with the basic ONIE installation.

I’m pretty sure I have already rebooted RIO0001 for and checked that 
RARE/freeRtr could restart flawlessly. 


So something has happened in terms of software (upgrade upgrade ...)

Do you know by any chances if anything happened on the WEDGE ?
Software change, upgrade etc.

I don’t have much time this evening/tonight but I’ll have another fresh look 
tomorrow.

À bientôt,
--  Frederic
