Hello,

couple of days ago my Cisco 2821 router started crashing every 4-5 hours with the same error. As I remember, no configuration changes were made almost for 2 weeks.

There is the context:

Thank you very much.

The router is crashing due to CSCsv13099. You need a valid CCO id to view the details. Upgrade IOS to 12.4(24)T1 or higher

It's a bug.


Load the next level of IOS into the CF.  If it crashes once more, the new IOS will load.

Do you have the crashinfo file?

Why don't you try to upgrade the IOS?

Here is it.

I have one more 2800 series router and it works OK with the same IOS.

I've used that and I don't see any issue.  I'm currently using 15.1(2)T1.

As long as you have enough DRAM and Flash to run it. Check the recommended values on CCO

Have 1024 mb RAM on it and unfortunately 64 mb CF, but I have one 128 mb from SanDisk vendor, hope it won't be a issue.

Minimum values are 512 mb RAM / 128 mb CF.

ISR G1 (except the 870) can support up to 2Gb CF.

Thank you for the info. It works great now, but I'm planning to try with c2800nm-advsecurityk9-mz.151-1.T.bin as I don't need all those features included into Advanced Enterprise Services.
