Cisco Switch Crashing - Log Included

Any ideas?

I would like to isolate this issue to 1 unit / component if possible. Otherwise, I will be forced to replace the entire stack.

This is a stack of 6 Cisco 3750 switches.

The stack has been locking up / crashing recently. Typically a power cycle is required to restore functionality. I have it scheduled for replacement in a week or two.

This is an example of my logs on this stack:

if you not have this command you need to contact the TAC:
Error Message    PLATFORM_RPC-3-MSG_THROTTLED: RPC Msg Dropped by throttle mechanism:
type [int], class [int], max_msg [int], total throttled [int]

Explanation    This message means that there are too many outgoing messages queued for a message class. An RSP message was dropped. The first [int] is the message type, the second [int] is the message class, the third [int] is the maximum number of messages that can be queued before throttling occurs, and the last [int] is the total number of messages that have been throttled.

Recommended Action    Copy the error message exactly as it appears on the console or in the system log, call your Cisco technical support representative, and provide the representative with the gathered information.
