[Bug 579369] New: pulseaudio: 100% cpu usage
http://bugzilla.novell.com/show_bug.cgi?id=579369 http://bugzilla.novell.com/show_bug.cgi?id=579369#c0 Summary: pulseaudio: 100% cpu usage Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: Other OS/Version: openSUSE 11.2 Status: NEW Severity: Normal Priority: P5 - None Component: Sound AssignedTo: tiwai@novell.com ReportedBy: suse-beta@cboltz.de QAContact: qa@suse.de Found By: Beta-Customer Blocker: --- pulseaudio currently uses 100% CPU of my system. According to strace, it seems to do the same thing in an endless loop (about 13000 times per second while stracing it): ppoll([{fd=4, events=POLLIN}, {fd=27, events=POLLIN}, {fd=28, events=0}, {fd=33, events=POLLIN}, {fd=9, events=POLLIN}, {fd=22, events=POLLIN}, {fd=29, events=POLLIN}, {fd=32, events=POLLIN|POLLERR|POLLHUP}, {fd=32, events=0}, {fd=31, events=POLLIN}, {fd=30, events=POLLIN}, {fd=23, events=POLLIN}, {fd=26, events=POLLIN}, {fd=16, events=POLLIN}, {fd=19, events=POLLIN}, {fd=15, events=POLLIN|POLLERR|POLLHUP}, {fd=15, events=0}, {fd=14, events=POLLIN}, {fd=13, events=POLLIN}, {fd=6, events=POLLIN}], 20, NULL, NULL, 8) = 1 ([{fd=28, revents=POLLHUP}]) I attached gdb to it, result: (gdb) bt #0 0x00007fae575e4f57 in ppoll () from /lib64/libc.so.6 #1 0x00007fae59d03457 in pa_mainloop_poll () from /usr/lib64/libpulse.so.0 #2 0x00007fae59d04799 in pa_mainloop_iterate () from /usr/lib64/libpulse.so.0 #3 0x00007fae59d04850 in pa_mainloop_run () from /usr/lib64/libpulse.so.0 #4 0x000000000040a19a in main () Unfortunately I have no idea what caused pulseaudio to take all the CPU, therefore I can't offer a reproducer. I hope the infos in this bugreport can give you some insight. Some details about my system: - Dell Vostro 1710 laptop - openSUSE 11.2 64bit with all updates + nearly all test updates as of today - KDE 4 - running programs: several KDE apps (KMail, Gwenview, Konqueror etc.) + GIMP - I also used mplayer tonight (not sure if is related) - pulseaudio runs with normal (nearly no) cpu usage again after killing the process taking 100% cpu # hwinfo --sound 13: PCI 1b.0: 0403 Audio device [Created at pci.318] UDI: /org/freedesktop/Hal/devices/pci_8086_284b Unique ID: u1Nb.6k+7+p1inn5 SysFS ID: /devices/pci0000:00/0000:00:1b.0 SysFS BusID: 0000:00:1b.0 Hardware Class: sound Model: "Intel 82801H (ICH8 Family) HD Audio Controller" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x284b "82801H (ICH8 Family) HD Audio Controller" SubVendor: pci 0x1028 "Dell" SubDevice: pci 0x0275 Revision: 0x03 Driver: "HDA Intel" Driver Modules: "snd_hda_intel" Memory Range: 0xf8300000-0xf8303fff (rw,non-prefetchable) IRQ: 22 (31634 events) Module Alias: "pci:v00008086d0000284Bsv00001028sd00000275bc04sc03i00" Driver Info #0: Driver Status: snd_hda_intel is active Driver Activation Cmd: "modprobe snd_hda_intel" Config Status: cfg=no, avail=yes, need=no, active=unknown BTW: The symptoms match bug 558119, but I don't have any "via" driver loaded. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I just see that there's a pulseaudio update in the test updates (libpulse-browse0, patch 1952). This patch is not (yet) installed on my system. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If yes, try to update pulseaudio packages in OBS multimedia:libs repo. And/or, try alsa-driver-kmp in OBS multimedia:audio:KMP repo for upgrading to the latest alsa-driver. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The problem is that I have no idea what caused pulseaudio to take 100% cpu and therefore don't have a reproducer. Additionally this issue appears quite rarely which makes it even harder to tell if it is fixed or if it just didn't enter this bug again... I'll let this bug in needinfo for some weeks (or until it happens again). -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What I did this time: (besides the usual running KDE apps) - watch a movie in mplayer, pause it - start another instance of mplayer, watch a short movie section there, wait until it quits - (try to) continue in the first mplayer - it aborted because device was locked by another process (huh? the second one was quit before...) - start mplayer again Resetting needinfo for now since the details above might give you some insight. (I'll try to upgrade to the buildservice packages in the next days and report back.) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Does this still happen with 12.2 versions?
I'm using Factory and didn't see this problem for a long time - but I'm not sure if my system is using pulseaudio at all (ps aux |grep pulse shows nothing while clementine plays some music). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
