The bcm56xxd daemon may restart and produce a core file. It then continues trying to program the DAG. This causes a system to go offline and stop processing traffic.


-- HA configured. -- Programming the DAG while it is under heavy load (i.e., a large number of objects that have to be programmed into the switches).



Fix Information

The bcm56xxd daemon no longer crashes while the DAG is being programmed.
