S-Series 

Symptoms
Syslog and the Message Log ('show support') contain one or more items similar to this:
<3>bcmStrat[2.bcmDPC]unit 0 (null) asserted

This may also be related to a condition causing high CPU utilization primarily from the Hardware Maintenance task (12846). 

Solution
Upgrade to firmware 7.21.02.0002 or higher.
Release notes state, in the 'Firmware Changes and Enhancements' section:
Platform
If ports are receiving traffic while their MAC chip is being initialized the MAC may mishandle these packets and cause errors similar to "1. Fuji RX MAIN intr: Fuji=8, Adr=0, Reg=0x00200040", "2. Fuji MAC MAIN intr: Fuji=0, Adr=0, Reg=0x00080000", "3. MEM_FAIL interrupt occurred on chip" (which resets blade), or one of several bcmstrat memory system parity errors sometimes reported as "bcmStrat[3.bcmDPC]unit 0 (null) asserted ". The "parity" and "null" messages are displayed constantly and result in high CPU utilization.

If the issue persists after upgrade, please contact the GTAC for assistance.
