We had a problem on carde #1 that led to a problem on the communication bus between the cards :

The routing was completely stopped on the router when all the cards were up. After a forced reboot on card #1, card #2 has taken control
and the routing was restablished.

Card #1 has restarted normalement. We are again in a normal functionning.
