Description of problem: nscd "forgets" hosts on hibernate/thaw cycle. Various programs fail etc. Version-Release number of selected component (if applicable): 2.9-2 How reproducible: Intermittent. Steps to Reproduce: 1. Hibernate a machine, then thaw. 2. Use a program such as Evo or screensaver to contact a host on the network. Actual results: Programs report that hosts are not there. Expected results: This worked in F-9. Additional info: Workaround is: service nscd stop rm -f /var/db/nscd/* service nscd start I first noticed that with gnome-screensaver authentication that pops up on thaw. Then I realized that Evo cannot get mail, reporting that the host isn't there.
This also helps: # nscd --invalidate=hosts
It works just fine for me. Run nscd in the foreground using nscd -d -d -d and show the output.
Isn't that a bummer. When you want the darn thing to fail - it doesn't. I haven't seen this for almost two weeks now...
The moment I said I didn't see it for two weeks, it happened. I'll attach first the strace output of the running nscd and also debug output of the 'ncsd -d -d -d', which I started after stopping the running nscd with 'service nscd stop'. Hope it helps.
Created attachment 326416 [details] Strace of the failing nscd This one was stated with 'service nscd start' before the system was hibernated. In other words, it was just a normal startup, no debugging at all turned on.
Created attachment 326417 [details] Debug output of nscd This one was started with nscd -d -d -d and output captured in this file, as instructed. Note that the user was in the end (after a few tries) able to supply the password on the gnome-screensaver lock screen successfully. I'm guessing nscd recovered from the failed condition eventually...
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '10'. 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 10'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 10 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 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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.
