Cisco 2821 crashes couple of times a day

[Safar Safarov]

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:

Do you have the crashinfo file?

Why don't you try to upgrade the IOS?

[Safar Safarov]

Here is it.

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

   Possible software fault. Upon reccurence,  please collect
   crashinfo, "show tech" and contact Cisco Technical Support.

It's a bug.

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

Is c2800nm-adventerprisek9-mz.151-1.T.bin OK?

[Leo Laohoo]

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

[Safar Safarov]

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.

[Leo Laohoo]

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.

[Safar Safarov]

Works perfect! Thank you all for your help.

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
