- On average mcpd takes more time to process large firewall rule stats ~20k, but sometimes it takes even longer. - MCPD abruptly removes the LACPD connection causing LACPD to restart. - Multiple MPCD query response exceeding messages and then lead to bcm core. Ex: 010e0004:4: MCPD query response exceeding 60 seconds
Bcm56xxd process will kill by sod due to the heartbeat missing. It impacts the traffic.
-- More(~20k) firewall rules configured along with pccd.overlap.check enabled -- mcpd is constantly busy taking ~20 seconds to process query_stats { fw_rule_stat { } } -- bcm56xxd replies to a query_stats { l2_forward_stat {} } query with every l2 address entry in ARL table
