[c-nsp] Weird error

Wed Feb 27 15:01:49 EST 2008

Ziv,

There are two issues here;

   1. your core concern - software forced crash
   2. the secondary concern - parity errors

To troubleshoot the software forced crash, Cisco will need extra information
like the crashinfo files, steps to recreate, sh tech and logs. While waiting
for these data, I'm sure if you tell Rodney the IOS image running on this
box, he'll be able to take a look at IOS source code to shed further light
on why and when we call %SYS-1-MTNOTFENCED - which by the way is a pretty
serious error per it's severity - 1.

The natural first step resolution for multiple parity errors is to replace
the memory.

Shalom
eninja
ps. FYI most people on this list don't have visibility into IOS internals
hence their silence of these types of issues.
