Description Robin Green 2005-04-22 21:29:38 UTC
Description of problem: Some of my applications are reporting random "file not found" or "no such file or directory" errors, exclusively with *opened* files or sockets, since either my latest kernel upgrade or a recent one (I don't remember exactly when it started happening). I am not using NFS, but see also bug 144556. A typical error is an application, such as psi or pan, crashing due to an X I/O error, with "file not found" sometimes given as the reason. Another symptom is this non-fatal stack trace from a Java program, Azureus: DEBUG::Fri Apr 22 19:51:02 BST 2005 java.io.IOException: No such file or directory at sun.nio.ch.IOUtil.drain(Native Method) at sun.nio.ch.PollSelectorImpl.doSelect(PollSelectorImpl.java:66) at sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:69) at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:80) at com.aelitis.azureus.core.networkmanager.VirtualChannelSelector.select(VirtualChannelSelector.java:239) at com.aelitis.azureus.core.networkmanager.WriteController.writeSelectorLoop(WriteController.java:74) at com.aelitis.azureus.core.networkmanager.WriteController.access$0(WriteController.java:72) at com.aelitis.azureus.core.networkmanager.WriteController$1.runSupport(WriteController.java:52) at org.gudy.azureus2.core3.util.AEThread.run(AEThread.java:45) I believe both of these errors are symptomatic of the same problem, which is that the kernel (or perhaps glibc) seems to be ocassionally reporting a file not found error for operations on open file descriptors. These errors happen on the order of once or twice in an hour, or less, usually when I'm not at the machine. Version-Release number of selected component (if applicable): kernel-2.6.11-1.1253_FC4 How reproducible: Not consistently reproducible Additional information: glibc-2.3.4-21
Comment 1 charlesc-fedoracore-bugzilla 2005-04-29 00:43:51 UTC
I believe this one has been around for a while; a customer of mine is seeing processes dying on Fedora Core 2 with at least kernel-2.6.9-1.6_FC2 and kernel-2.6.10-1.771_FC2. The system seems to fail to open files even when plenty of fds are available as well.
Comment 2 Dave Jones 2005-06-27 23:23:38 UTC
Mass update of -test bugs to update version to fc4. (Please retest on final release, and report results if you have not already done so). Thanks.
Comment 3 Dave Jones 2005-07-15 21:16:39 UTC
[This comment has been added as a mass update for all FC4 kernel bugs. If you have migrated this bug from an FC3 bug today, ignore this comment.] Please retest your problem with todays 2.6.12-1.1398_FC4 update. If your problem involved being unable to boot, or some hardware not being detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE* installing any kernel updates. If in doubt, you can recreate this file using.. mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak mv /etc/modprobe.conf /etc/modprobe.conf.bak kudzu Thank you.

I have not seen this bug for weeks, so closing.
