[c-nsp] 2811 crash...

[Brad Beck]

Hi,

I've got a 2811 that crashed with a bus error within a few hours of enabling Netflow export.  I haven't opened a TAC case yet, but my curiousity was aroused by the address at which the error occured.... "0xDEADBEF3".  This could almost be pronounced "Dead Beef"....  

"System returned to ROM by bus error at PC 0x41165340, address 0xDEADBEF3 at 20:33"

Any thoughts on this?  Is netflow export on a router passing only ~500Kb/s peak typically problematic?

thanks!
