Under heavy load, bcm56xxd may not get enough CPU cycles to finish some of its operations and activate the watchdog process. In that case, sod will suspect that bcm56xxd has halted and terminate the process.
The switch will not operate during the restart, and traffic might be interrupted.
When the system is very busy, tmm has higher execute priority, and bcm56xxd does not have enough CPU cycles.
Reduce the traffic to make the system less busy.
The system now has bcm56xxd activate the watchdog so that sod does not terminate the bcm56xxd process.
