| What we were seeing with the 801 in 3.x days involved the CSS

| downloads over modems would lose their flow on the CSS and then receive a
| TCP reset from the server.
|
| Also during the same period we were regularly locking up the CSS's
| because of the issues with the backplane and the number of packets we were
| pushing under load. Our application involved 100k+ of sessions and smaller
| then average packet size so our load was fairly extreme. The timeouts came
| first and then once load increased, around 480Mb/s in our case, the box
| would reboot. Later versions of 4.x solved most of the problems after a lot
| of beta code from Cisco though we did have to distribute the traffic over
| more interfaces (and an Active-Active setup helped) to solve the TCP reset
| issue.
|
| While you may be running later versions of the code, it is
| possible that you are hitting limitations of the box or maybe your
| architecture needs to be changed (though it seems really unlikely). I'd
| recommend doing packet traces at client side and server side... even if
| it's just snoop or tcpdump. Ethereal on Linux is great for low bandwidth
| captures if you don't have Sniffer. Then call Cisco and have them walk you
| through tracing flows and checking the resources on the CSS.
