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.
