NPE-G1 - Reset by hardware watchdog timeout with no traceback : CSCea25622

[jason.farber]

We have had 2 7206vxrs with NPE-G1s that just reboot every 4-6 weeks on their own. It appears to be this bug, that has no workaround and Cisco does not yet know what causes it. The two NPE-G1s had different versions of code, one had 12.1.13E and the other had 12.2.4. Has anyone else had similar issues?

I thought with the NPE-G1 having been out for a while I'd be safe from new product instabilities but apparently not.

That bug is reported agains E releases. Now you do have one 7200 on 12.2.4 so do you see the same issue on that version too?

If not, then you can go for that version..

[jason.farber]

No, one of the two NPE-G1s was at that version and I had it set up to go to 12.1.14e, meaning the code was on the flash and all I had to do was go through our change management process to implement it. But before I could do that, the router rebooted due a watchdog reset, the same as our 12.1.14e npe-g1. So the bug does seem to affect both versions. According to TAC, there is no software fix available.

The B on 12.2.4B stands for Broadband, right?

[tepatel]

The fix or workaround for that bug is still not available. So stay away from 12.1.14E if that bug is bothering you too much.
