[Bug 1030828] New: systemd-coredump[20814]: Process 20787 (gnome-shell) of user 1000 dumped core.
http://bugzilla.opensuse.org/show_bug.cgi?id=1030828 Bug ID: 1030828 Summary: systemd-coredump[20814]: Process 20787 (gnome-shell) of user 1000 dumped core. Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.2 Hardware: x86-64 OS: openSUSE 42.2 Status: NEW Severity: Critical Priority: P5 - None Component: GNOME Assignee: bnc-team-gnome@forge.provo.novell.com Reporter: Ulrich.Windl@rz.uni-regensburg.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I had cleanly unmountzed an USB memory stick via file manager, then unplugged it. After that I noticed that the system is unresponsive. Soon after window decorations vanished from my windows, and CPU load was very high (seeing three systemd-coredump processes taking 100% CPU each). Then the whole GNOME session was aborted. I needed two attempts to reestablish a new GNOME session. Unfortunately there are no good logs, and I couldn't find the cores. gnome-shell-3.20.4-8.1.x86_64 Mar 24 09:24:26 pc packagekitd[21536]: (packagekitd:21536): GLib-CRITICAL **: Source ID 15 was not found when attempting to remove it Mar 24 09:24:30 pc dbus[1340]: [system] Failed to activate service 'org.bluez': timed out Mar 24 09:24:30 pc pulseaudio[21504]: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply.

Interesting - there are two GNOME releases difference (3.20 in Leap vs 3.24 in TW) Please extract a backtrace: coredumpctl gdb gnome-shell it will likely tell you to install missing debuginfo packagges - do so, to get a useful trace at the (gdb) prompt, type: thread apply all bt full (eedinfo set - waiting for backtrace) -- You are receiving this mail because: You are on the CC list for the bug.

I've been trying to get it... but apparently, systemd is still telling me it can't coredump because of limited resources, despite having this in limits.conf (and even a full reboot): * soft core unlimited * hard core unlimited Running your command as-is gives me this output. To be noted that nothing shows up in "coredumpctl list". sudo coredumpctl gdb gnome-shell PID: 9555 (gnome-shell) UID: 1000 (fblaise) GID: 100 (users) Signal: 11 (SEGV) Timestamp: Thu 2017-07-27 11:13:04 CEST (2min 22s ago) Command Line: /usr/bin/gnome-shell Executable: /usr/bin/gnome-shell Control Group: /user.slice/user-1000.slice/session-1.scope Unit: session-1.scope Slice: user-1000.slice Session: 1 Owner UID: 1000 (fblaise) Boot ID: 3cf8c8daf6da4996ab3f2a8478489132 Machine ID: 30ea28100486a6a2e8e4bd2258b1bb01 Hostname: gimli Storage: none Message: Process 9555 (gnome-shell) of user 1000 dumped core. Coredump entry has no core attached (neither internally in the journal nor externally on disk). If I try to gdb to the actual running process such as: gdb -p [one-of-gnome-shell-pid] I have to get to another tty to kill gdb, as it freezes my entire desktop. So I am currently down to try to demistify coredumps with systemd... sorry, it's been a while since I had to troubleshoot anything. -- You are receiving this mail because: You are on the CC list for the bug.

I know of at least one that causes the occasional crash and reload of gnome-shell leaving a coredump behind, namely the "Random Wallpaper" extension. But there may be others. Does starting with all extensions disabled (e.g. from gnome-tweak-tool -> Extensions) help? -- You are receiving this mail because: You are on the CC list for the bug.

Open gnome-tweak-tool and go to the Extensions tab, all installed extensions should be listed there. -- You are receiving this mail because: You are on the CC list for the bug.

Hey Fred, Sorry, I have no idea why this is not working in your case. On my system, it just works, I haven't had to modify any configuration from the default TW installation to get this working. -- You are receiving this mail because: You are on the CC list for the bug.

Once disabled, it is not crashing anymore. (https://extensions.gnome.org/extension/1064/system-monitor/) As far as I am concerned, this is not a bug then. Thanks!
