Symptoms
The output of a 'show system utilization' command displays high CPU utilization on the "Hardware Maintenance" task.
Possible module reset.
In the output of a 'show support' command, the message log contains one or more items similar to this:
<3>bcmStrat[2.bcmDPC]unit 0 L3_ENTRY_ONLY entry 2139 parity error

Solution/Workaround
Please contact the GTAC for assistance. 

Workaround:
A module reset, which occurs automatically with firmware 7.03.xx.xxxx and higher, will temporarily clear the high CPU utilization. With lower firmware, the user may manually issue a reset for this purpose.
