[c-nsp] Cisco 7206VXR - IOS 12.4(12) - Bus Error Crash

[Werner Detter]

Hi everybody,

tonight, one of our 7206VXR (NPE-400) running c7200-ik9s-mz.124-12.bin
crashed due to a bus error (bus error at PC 0x6013C4D8, address 0x64588700).

I'm trying to figure out what exactly caused this bus error using 'show stacks'
and 'show tech' and i've found these lines:


%ALIGN-1-FATAL: Illegal access to a low address 03:47:34 UTC Wed Mar 12 2008
  addr=0x18, pc=0x6013C4D8 , ra=0x6087DE28 , sp=0x644D8DF0

%ALIGN-1-FATAL: Illegal access to a low address 03:47:34 UTC Wed Mar 12 2008
  addr=0x18, pc=0x6013C4D8 , ra=0x6087DE28 , sp=0x644D8DF0

03:47:34 UTC Wed Mar 12 2008: TLB (load or instruction fetch) exception, CPU signal 10, PC = 0x6013C4D8


Has anyone seen this error on a 7206VXR ?

Thank you,
Werner
