A reliable method for reproducing the problem would be an important first
step. I can give it a try on my Rhine-III gear, but the bug report is a
bit thin on details.

This bug is hard-catched. At regular (one second period) network loading, into keep-alive connection, problem can appear after up to week of normal work.

But into not keep-alive mode, reconnection make at any regular request, this problem can appear after up to day normal work.

Regular load is made by OpenSCADA system and average value is 40 КB/s.

What can I help you for problem detect?
I can get some information from system into problem appear time.

I was about to blame my Xavi ADSL modem router until I found this entry. Mine is a Rhine-II (Debian amd64, 2.6.32-trunk) which happens to lost Internet connectivity after few or several minutes of network inactivity. Pinging the router works fine though. The only way I have of preserving Internet connectivity is keeping a constant network flow (a BitTorrent client, for instance) and even that fails sometimes (but the torrent keeps alive, just I cannot link to any other network host).

Another box (running Windows XP) simultaneously attached to the same router shows no network failures.

Closing as obsolete, if this is still seen with modern kernels please update the bug
