I also experience this bug. I'm running Fedora 9 x86_64, fully updated: kernel-2.6.26.5-45.fc9.x86_64 pulseaudio-0.9.10-2.fc9.x86_64 alsa-plugins-pulseaudio-1.0.16-4.fc9.x86_64 alsa-utils-1.0.17-2.fc9.x86_64 alsa-lib-1.0.17-2.fc9.x86_64 After running for awhile, the pulseaudio daemon dies. If I restart it on the terminal, after awhile I get this: Soft CPU time limit exhausted, terminating. Hard CPU time limit exhausted, terminating forcibly. Aborted This may be related to the adobe flash player crashing (which seems to happen a lot on my system). However, it does not happen every time the flash player crashes, nor does the flash player crash every time it happens. I haven't changed the default pulseaudio configuration, though I upgraded the system from F7 -> F8 -> F9 through yum update. http://www.pulseaudio.org/ticket/207 This pulseaudio bug may be related. Why isn't the pulseaudio bugtracker an option in external bugs in bugzilla? Matthew: I am quite sure that I have seen the problem on an un-resumed machine. I also thought this (or a similar) problem was related to flash. But the problem has also appeared without flash or nspluginwrapper running, just pidgin and rhythmbox playing ogg. I don't know how much the audio infrastructure has changed between f9 and f10, but I don't think we should assume that they have similar problems. I never suspend or hibernate my machine, and I still get this problem. Since the symptom is so similar it seems reasonable that they are related problems. I am seeing this problem too. pulseaudio commits suicide after playing ~ 1 cd worth of music in rhythmbox. The only other client open was pavucontrol. Full log of pa -vvv available upon request. This is perhaps the same as or related to Bug 466316 - Daemon hangs, starts eating up CPU cycles, rhythmbox freezes Bug 466338 - I: memblock.c: Pool full I just got Oct 16 17:33:21 dev-mk pulseaudio[3265]: cpulimit.c: Recevied request to terminate due to CPU overload. That was when playing an ogg from rhythmbox. flash-plugin not installed. (livna plugins is installed but not used.) Rhythmbox was hanging and didn't redraw after that. I assume that that is a rhythmbox bug ... 5 seconds before the suicide something (the pulseaudio process, I assume) started using 100% of one cpu (on my dual-core system). So the problem isn't that pulseaudio terminates, but that it starts using all cpu. With log-level = debug nothing was logged when it started eating cpu. I am setting the severity to high. Which driver is this? I don't know how to answer that - does the following answer it?

Yes it does. Could you please generate a bit of profiling for me? http://pulseaudio.org/wiki/HowToUseOProfile This will help me understand where exactly PA starts to spin in a 100%-CPU-Loop. Please make sure to run the newest kernel from rawhide when doing this. Oh and this actually looks like yet another dupe of 462200... *** This bug has been marked as a duplicate of bug 462200 *** I can confirm that with the latest updates it seems to work a lot better.
