I am talking about packet loss, crash, packet loss, crash, packet loss,
crash and so on.

I understand the point of image/damage control, thought at this time
what I
am interested is not a reply from Cisco along the lines of "please send
the
'sh tech'". Rather I am interested in hearing from people who are using
GSRs
in non-lab environments about similiar issues since I happen to have a
hunch
that should I not get that background information myself, I would have a
problem convincing people that the issue had even been there...=20
So, returning to my original question...
Does anyone know of "interesting" crashes related to CAR on GSRs running
IOS release close to what I have described... (Since during the past
tests
the same router in the same setup with the same IOS ran just fine when
it
was applying same type of rate-limiting to 3x as much traffic on a
different
sub-interface)
Thanks,
Alex
