Router(boot)# processor memory parity error at PC 0x60245050

I have a router that is having some hardware

trouble and frequently reboots itself due to processor memory parity errors.

It usually recovers automatically, but today the router rebooted however it did not fully recover

and it had the word (boot) in the prompt, i.e.

Router_No_2(boot)#

I had customers waiting and complaining, so I quickly did a 'reload' and now things are up and running and now the word (boot) is no longer in the prompt.

This is happening more frequently now and I know the

router needs to be replaced asap.

My question is really twofold:

(1) Why did the router not make it fully up one

time and had the word (boot) in the prompt.

(2) Has anyone seen this type of memory parify

error before and have any ideas how bad this

is going to get? i.e. soon completely dead?

Here is the current show version:

Thanks for the response.

I have seen the doc you mentioned, but it was good to get a reminder. I hadn't read it in a while..

As the document explains, since this router is a

Cisco 4500/4700 series running IOS Version 12.2(3),

there is no crashinfo available since this is pre-

IOS Ver 12.2(10).

I also realize that the recommendation is to replace

the DRAM as a first step and I will likely replace

the router before anything else.

Again, I know the hardware is sick and dying and was

just curious as to why the router booted up in the

(boot)# prompt. Anyone have any ideas on why the

router booted from BootROM even though the config

register was set correctly?

It has since booted up correctly ..

Thanks.
