Hello!

> 2.4.6 machine pushes lots of data on _first_ TCP connection after boot

Lots? I see only about 24K of data transmitted in both your samples.

Actually, the problem is more or less clear from your /proc/net/tcp.
You use some funny device or netfilter plugin, which leak memory.
You can look into 7th column of /proc/net/tcp to estimate amount of leaked
buffers. When it reaches ~15, connection stalls. Seems, it raises
monotonically, so that it looks like all the buffers leak.

What is output device?

Alexey
