Subject: Re: [bug] stuck localhost TCP connections, v2.6.26-rc3+
Date: Thursday, May 29, 2008 - 9:08 am

btw., i now also have a hung socket over real network:

titan:~> netstat -nt
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State
tcp        0  86752 10.0.1.14:49921             10.0.1.16:3632              ESTABLISHED

(the scenario is similar to the incident i've analyzed before, so i wont 
repeat the tcpdump, etc.)

	Ingo
