	I'm using 2.6.26.

	We've been discussing this issue here:


	It's a huge thread and it seems that my problem isn't related
to the problem of the first poster (tcp_frto).

	I've been exchange many mails with Ilpo Järvinen, but we
couldn't figure it out, since it happens randomly.

	And yes, I think you're right, it can be probably a kernel
issue. But it's been very difficult to debug this.

	But, as you said, it seems to be a kernel issue. I'll keep
trying to figure it.

	Thank you very much!
