** Summary changed: - PulseAudio gets killed by SIGXCPU + PulseAudio gets killed mysteriously
** Description changed: Binary package hint: pulseaudio I'm using Ubuntu Studio 9.04 and have enabled PulseAudio (0.9.14-0ubuntu20) with real time enabled. While playing music I noticed that the audio output would suddenly stop, though Amarok kept on as if everything was fine. I noticed that pulseaudio was no longer running, when running it from the command line I observed again the same behavior and the last output line from PulseAudio was "Killed". By attaching strace with -e trace=signal I found that it would occasionally get a SIGXCPU signal. On the 3rd signal, pulseaudio gets killed, presumably by the Linux kernel. - I resolved this issue on my system by setting "no-cpu-limit = yes" in - the /etc/pulse/daemon.conf file. It seems by default the soft limit of - "Max cpu time" was set to 10ms (as reported from /proc/PID/limits), - which was getting exceeded. Since PulseAudio has been otherwise running - just fine, I think this rlimit setting is too conservative and should - probably be raised (not sure if this is possible via the daemon.conf). - One additional note is that I changed the resample-method to speex- - float-1 from the default of src-linear. + By setting "no-cpu-limit = yes" in the /etc/pulse/daemon.conf file, it + got rid of the SIGXCPU signals, which didn't seem to be the problem, + since it is still getting a SIGKILL signal.

I'm at a loss as to where the SIGKILL is coming from. -- PulseAudio gets killed mysteriously https://bugs.launchpad.net/bugs/367671 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
