I still propose that you tcpdump it, then I can tell you (I know
enough about Thomas' case but yours has a large number of
unknowns)... :-) I don't know why 2.6.24 didn't suffer from the
problem as FRTO was enabled already in it. The command you need
to create dump.log file:

# tcpdump -w dump.log -i <iface> host <peerip>

...you need root rights (or sudo) to do the capturing.
	Ok, but the problem is that the bug doesn't happen
frequently... yesterday I waited for it to happen and nothing
happened :). I'll keep watching it... if I can get the dump, I send it.
Ok, thanks for your efforts... These are often hard to reproduce because
some not that likely pattern needs to happen and such things is often not
easily controllable (if it is at all possible to influence the 
likelyhoods).
