[c-nsp] cisco memory bug / propabilities?

[Frank Bulk]

We provided a list of line card serial numbers to our Cisco account manager
and he was able to check if there were any at-risk cards.  Two weeks later
he confirmed there weren't, but I still had spares nearby.

Hi,

there's the infamous cisco memory bug "reboot and see your boxes die" - with
the recent IOS software fixes, I have a couple of 6500s that need a reboot
now, and I'm a bit scared - read: do I plan for "I reboot as usual, and
there is a remote chance that hardware will not come back, so ensure 
a longer-than-planned outage is acceptable", or "I really should have a 
full set of spare boards sitting beside the to-be-rebooted box, because 
90% of all boards will die"...?

What are *your* experiences with dieing cisco memory, in particular on
6500s?

I've heard horror storries from ASA owners, but not very much from 6500 
owners yet...  (and that's not because "nobody but me is using them 
anymore").

The advisory

is not very specific...
