	I have the same problem with connections stalled and the only
"workaround" I found is to trigger a nmap -sS to the server with the
stalled connection. I don't know why, but this helps it come back alive
again...

	But it surely is a Linux network bug introduced in 2.6.25
kernel, I'm sure (with 2.6.24 and below it doesn't happen, or maybe
we're talking about different symptoms of the same bug or 2 different
similar bugs... who knows?).

	I use the tg3 kernel module for the NIC... the same
configuration of the kernel doesn't trigger the bug with other types of
nics... so could we suspect of tg3 kernel module?

	What's your NIC?
