Can you help me answer on some questions:

1. Where problem: Software or Hardware?

2. Why two crashinfo files?

Hi Konstantin,

SO

%C6K_PLATFORM-2-PEER_RESET: RP is being reset by the SP

means that SP crashed first and valid crashinfo is in sup-bootdisk. That one says:

Cache error detected!
  CPO_ECC     (reg 26/0): 0x00000084
  CPO_CACHERI (reg 27/0): 0x20000000
  CP0_CAUSE   (reg 13/0): 0x00000C00
Real cache error detected.  System will be halted.
Error: Primary instr cache, fields: data,
Actual physical addr 0x00000000,
virtual address is imprecise.
Imprecise Data Parity Error
Imprecise Data Parity Error

So this is Cache Parity error.

A parity error can happen in all type of RAM, regardless of the manufacturing. There are two kinds of parity errors:

Soft parity errors
These errors occur when an energy level within the chip (for example, a one or a zero) changes, most often due to radiation. When referenced by the CPU, such errors cause the system to crash. In case of a soft parity error, there is no need to swap the board or any of the components.

Hard parity errors
These errors occur when there is a chip or board failure that corrupts data. In this case, you need to re-seat or replace the affected component, which usually involves a memory chip swap or a board swap.

At the first occurrence it is not possible to distinguish between a soft or hard parity errors. From experience, most parity occurrences are soft parity errors, and you can usually dismiss them. Studies have shown that soft parity errors are 10 to 100 times more frequent than hard parity errors. Therefore, Cisco highly recommends you to wait for a second parity error on that particular affected component before you replace anything. This greatly reduces the impact on your network.

To learn more about Parity Errors please check the following CCO documentations:
https://www.cisco.com/en/US/products/hw/routers/ps341/products_tech_note09186a0080094793.shtml
http://www.cisco.com/en/US/products/hw/routers/ps167/products_tech_note09186a0080094340.shtml

So if it first occurrence - then just monitor as ususally that is transient. If will be seen again in short period - replace Supervisor.

Hope it helps,

Nik
