Well, if the memory errors corrupts the forwarding table placed on the
line cards or something similar, and still keeps its adjacancies up, then
you can get these problems. I've seen it happen on route-cache boxes where
certain entries in the ip-forwarding table was corrupted and thus
incorrectly routed.
It could be that they ran out of memory on linecards as well, perhaps
injected too many routes etc, and lost dCEF (dunno if the problems was on
gsr or juniper), been there, done that.
