ASR 1004 crashed

Software caused reload.  Most likely caused by the constant EIGRP adjacency constantly going up and down.

ASR 1004 crashed

so what is the solution?

ASR 1004 crashed

Fix your EIGRP adjacency first.  Why is the adjacency constantly going up and down?

Before this crash, the ASR was up for about 1 week and 4 days.  So I will have to presume that it must've been crashing.  So fix the underlying issue before we tackle the next possibility.

ASR 1004 crashed

it is the first crash, eigrp should not crash ASR.

Re: ASR 1004 crashed

I'm not discounting an IOS bug, however, seconds before the crashed occur nothing is showing that it's caused by an IOS bug.  Instead, the logs is showing that your EIGRP adjacencies keep going down and up and then the appliance crashed.

If you believe that unstable EIGRP adjacencies are not causing the issue (particularly the logging side) then disable logging (not recommendable).

Otherwise another option is to upgrade your IOS.

Re: ASR 1004 crashed

Eigrp is stable. Before the crash, I think the main dmvpn tunnel was down, when it went up, routers' control plane did not handle the all eigrp requests and crashed. But it should not be crashed.

Re: ASR 1004 crashed

Now that I can open the file on my PC I can see this;

Dec  6 2011 18:48:18.173 : %ASR1000_INFRA-4-NO_PUNT_KEEPALIVE:  Keepalive not received for 300 seconds

Dec  6 2011 18:48:18.173 : %ASR1000_INFRA-2-FATAL_NO_PUNT_KEEPALIVE:  Keepalive not received for 300 seconds resetting

The reason for reset is that the RP lost contact with the ESP (forwarding engine) and reloaded the system.

I think your version is current enough that what the ESP was doing at the time was also captured (enhancement added due to this CSCtl92129) but you will still need TAC to look into it further.

ASR 1004 crashed

It would be rediculous route flaps crash Cisco core routers. We have quite a few crashes on our main gateway ASR1006 with dual RP1 which cause P1 network outage for us.

Our network staff start to lose confidence on the ASR, if there are choice please don't use it as the core router.

ASR 1004 crashed

I've got a few ASR 1002 and I've never had a crash.

Granted the IOS is always (and I mean ALWAYS) gets upgraded.

Our routers are used for internet gateway with 1 Gbps connection.
