Bug 503181

Yes, although there are attempts to workaround this issue in pam_namespace, it would be better if the workaround was not necessary (and I think there were already attempts to fix it some time ago).

Here is another candidate for cleanup according to man Xserver:
/tmp/rcXn - Kerberos 5 replay cache for display number n

It seems to be possible to work around /tmp/.X11-unix, but a short search did not yield any information about how to do this for the lock files properly if one does not use only one Xserver.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

The replay cache isn't a real thing anymore, we haven't had working krb5 auth in ages.

The lock file I'm pretty sure is just garbage.  bind() will fail anyway.  And as for the X socket, I'm not going to move it, because there _is_ software that expects it to be there (buggy, but), and that expectation predates the FHS by years.  However, X works just fine with /tmp polyinstantiated, because we also listen on an abstract namespace socket.

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command

yum upgrade --enablerepo='*-updates-testing'

Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD .

Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.

If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.

[This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]

The /tmp/.X0-lock and /tmp/.X11-unix files are still there in F12.

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Given that as Adam explains in comment 4 we've no intention to move the socket, and that this has seen no real activity since it was first filed in 2009, I'm going to close this one.
