Bug Description
OS: Lucid 10.04.1 LTS, upgraded from Karmic 9.10
If too much information is sent to an unresponsive network connection, the connection seems to 'fail' and stops working. The unresponsive network connection is usually the result of a proxy or NAT router restarting.
Steps to duplicate in 10.04:
1) set up "ping -f google.com -i 10"
2) set up "ping -f google.com -i 1"
3) restart router
Result: the flood ping with interval 10 will show one or two dropped packets while the router is restarting, and then will show no further errors. The flood ping with interval 1 will continue to show dropped packets after the router has restarted, as too much information is in the connection buffer or something.
This also applies to IM connections (tested with Pidgin connected to MSN). If update information is sent while the router is restarting, the connection to the server 'stalls' and is only reset by the application after 15 minutes. If no information is sent while the router is restarting, the connection works fine immediately after the router has finished restarting and connected to ISP.

Tested this on 10.04 32-bit from a Live usb. First test with 10-sec interval stalled when restarting router, but with a 20-sec interval, there was only one missed packet and then resumed normal operation. Meanwhile the 1-sec interval ping completely stalled even after the router finished restarting.
