Severity: 3-Major


The BCM daemon deletes entries from tables during blade to blade failover. If tables are very large, the entry-by-entry deletion may take too long, such that the daemon is restarted by the watchdog timeout.


There is a BCM core file on the primary blade after the failover.


Very large L2 tables during blade-to-blade failover.



Fix Information

The system now maintains the watchdog while deleting large tables, so this issue no longer occurs.
