Bug 438414

Possibly caused by PID namespaces being enabled. They are disabled starting with
2.6.24.4-63, so see if that fixes this bug.

kernel-2.6.24.4-63.fc8 has been submitted as an update for Fedora 8

What do you mean by PID namespaces?  Would there be a pointer to the patch?

CONFIG_PID_NS in the upstream kernel enables a containers feature..

config PID_NS
        bool "PID Namespaces (EXPERIMENTAL)"
        default n
        depends on NAMESPACES && EXPERIMENTAL
        help
          Suport process id namespaces.  This allows having multiple
          process with the same pid as long as they are in different
          pid namespaces.  This is a building block of containers.

The containers stuff still seems to be in a state of flux, and afaik there's no
distro integration done yet, so this feature being disabled should have no
negative effect.

Does kernel -64 fix this bug?

kernel-2.6.24.4-64.fc8 has been pushed to the Fedora 8 stable repository.  If problems still persist, please make note of it in this bug report.

I've noticed regressions via the Frysk testsuite:

See comment #9, still seeing the problem.

Still happening in 2.6.25.4-10?

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '8'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 8's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 8 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days
