Subject: pulseaudio: Sometimes uses 100 % resources until killed.
Package: pulseaudio
Version: 0.9.17-1
Severity: normal
*** Please type your report below this line ***
Dear Debian hackers,
sometimes PulseAudio uses 100 % of the system resources (displayed by
`top`, %CPU). But I do not know how this is triggered and therefore I
cannot tell you a way to reproduce this.
I notice this problem, when the system feels slow or if I want to log
out and a dialog pops up, that an application is still running.
When this happens, I am also not able to play any music and get an error
message like »Connection refused.«. After killing the process,
everything works as expected again.
Last time I attached with gdb to the process and installed the debugging
symbols. You find the output of `t a a bt full` attached.
I did not file this report upstream yet, since they have already
released 0.9.18 [1]. But I did not see a related ticket [2] to my
problem.
Please tell me, how I can help further resolving this issue.
Thanks,
Paul
