Red Hat Bugzilla – Bug 207267
suffering delays and timeouts accessing web pages over firefox (seems to be no firefox bug though)
Last modified: 2008-05-06 12:22:29 EDT
Description of problem:
If I try to access some web pages like www.swox.org/gmp the response i bad.
Sometimes it just takes some minutes, sometimes it even results in a timeout.
The owner of the site (Torbjorn Granlund) mentioned that this is most likely a
bug in the linux kernel and can be worked around using the following command:
echo 0 >/proc/sys/net/ipv4/tcp_window_scaling
indeed this fixes the problem, but is there already an offical patch?
Version-Release number of selected component (if applicable):
Linux prime.mydomain 2.6.17-1.2187_FC5 #1 SMP Mon Sep 11 01:16:59 EDT 2006
x86_64 x86_64 x86_64 GNU/Linux
in about 90% of all cases
Steps to Reproduce:
1. open firefox
2. enter the url (see above)
4. wait longer :o)
timeouts. I haven't recognized somethink like that on other web sites yet, but
it seems strange to me, that I can do a workaround on my machine to solve this
problem. Is it really a problem on my machine?
the page is displayed after the usual
A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.

systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.

problem, please file a separate bug for the new problem.
This bug has been mass-closed along with all other bugs that
have been in NEEDINFO state for several months.

This appears to be a kernel bug and not a problem with the browser. I have
found two web pages that I cannot access: www.nohrsc.noaa.gov and
www.gpsworld.com, and found the same behavior on two different FC6 computers.
If I boot with a non-Fedora live CD, I can access these web sites. If I set up
an ssh tunnel, I can access these web sites. I have run tests with iptables and
selinux disabled, and the problem remained.
The simplest test is to run: wget -d www.nohrsc.noaa.gov
It consistently opens the socket, sends the http request, and then hangs:
Note the h/w I have is i386, and I'm running fc6.
It really is not a kernel bug. It is a bug with the routers between you and the
site that are visiting. To be specific it is firmware not adhering to the RFCs.
Just curious, what are the "non-Fedora" CDs that work with this? I would expect
that all of the new distros would have this problem since this functionality was
taken from upstream.
The live CD is Ubuntu 6.06.1, kernel is 2.6.15-26.
