http://bugzilla.opensuse.org/show_bug.cgi?id=1094763 Bug ID: 1094763 Summary: Fatal IO error 11 under heavy CPU load Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: rjhorn@alum.mit.edu QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- This is on a fresh install of Leap 15 followed by all current updates. The hardware was previously very stable with Leap 42.3. Various GUI applications fail for no obvious single reason. This affects at least firefox, google-chrome, VLC, and emacs-gtk. All failures are while the application is doing something. The errors captured from the command line for firefox and google-chrome are: - firefox: Fatal IO error 11 (Resource temporarily unavailable) on X server :1 - ERROR:chrome_browser_main_extra_parts_x11.cc(62)] X IO error received (X server probably went away) This takes place while the system is under heavy CPU load. The CPU is between 98-100% load with a large computational task at reduced priority. Failures occur at intervals from after a few minutes use to about an hours use, mostly of web browsing. When the heavy CPU load is removed, the error rate drops dramatically, perhaps to zero. No errors after 2 hours. -- You are receiving this mail because: You are on the CC list for the bug.
