Comment 1 Dave Jones 2005-06-04 01:50:54 EDT
can you try the latest test kernel from
http://people.redhat.com/davej/kernels/Fedora/FC3/  please ?

that has a bug involving tcp conntrack & localhost connections.
Comment 2 Dave Jones 2005-06-04 01:51:28 EDT
that should be 'that has a bug fix' obviously :-)
Comment 3 Dave Jones 2005-07-15 16:05:59 EDT
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.
Comment 4 Dave Jones 2005-10-02 20:47:21 EDT
This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
