Could you please provide backtrace of the segfault? Just for sure - check rpm -V coreutils and rpm -V glibc ... I doubt the real problem is directly in su (used too frequently to have general segfaults), but it would be good to address the issue - to prevent such failures in future. $ rpm -V coreutils $ rpm -V glibc ..?...... /usr/sbin/glibc_post_upgrade.i686 $ rpm -q coreutils coreutils-7.2-4.fc11.i586 $ rpm -q glibc glibc-2.10.1-5.i686 Unfortunately, I could not figure out how to get a coredump to appear. I used ulimit -c unlimited, but still no core file after the segmentation fault. Any ideas? I have since rebooted and the problem no longer occurs, but I will update this bug if it does occur again in the future. Right now, I am suspecting memory corruption in the hibernate/thaw process. The issue happened after several cycles of hibernate/thaw (I had not had a straight boot in a while). I realized that during the same time that the segmentation faults were happening, I was seeing general instability of several other processes. In particular, the following processes had problems: The gnome panel clock, an attempt to "yum install gnumeric", the bug notification tool (which spawned due to the clock failure). Please let me know if there is anything else I can provide. You could try to catch it with abrt (yum install abrt), start abrt daemon and try to report the crash with gui. Or you could try to get more details with debuginfo installed (debuginfo-install glibc coreutils) . About no coredumps - check what's ulimit -a showing ...Try to add "* hard core unlimited" to /etc/security/limits.conf - it might help as well... As there might be some memory corruption (I'm quite sure it is related to that hibernate/thaw process and not directly to su binary), reassigning to kernel, but keeping myself in cc... They might have some ideas how to get more about the failure. This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '11'. 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 11'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 11 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 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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. |
