[c-nsp] Warm upgrade?

[Łukasz Bromirski]

Hi,

One of my customers 7206VXR/NPE-G1 experienced today a strange thing:
it looks like it was warm-rebooted, but it wasn't ;) The router
rebooted and only thing in logs is:

00:00:10: %COMMON_FIB-3-TABLE: unknown-IPv6-table:0: table find
  -Traceback= 60775A04 605D2438 614F778C 614F7A48 605F7738 605F7684

              60808BA8 60808C38 6077BD60 6077C0CC

...I can trace the same message to this page:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123newft/123t/123t_11/gtwarmup.htm

which talks about warm upgrade feature but I'm sure it wasn't any
warm upgrade thing. Also, `sh ver' reports reboot by bus error, with
quite characteristic address (some process ran out of it's space?):

System returned to ROM by bus error at PC 0x61A4BA84, address 0xDEADBEEF

`show context' shows two regions with 0xDEADBEEF filler:

The router is running 12.2(25)S and has 1GB of RAM. It has also few BGP
sessions, but has more than 600MB free RAM and didn't experience
recently any heavy load (higher than about 10%). The sibling unit
running right underneath this and connected to other BGP peers didn't
encounter any problems at all.

Bug toolkit doesn't know about such problems. 12.2(25)S1 or RMA?
