Do you have any core dumps or stack traces? sorry for responding so late. no, up to now I don't have any trace files. I'm not an expert in doing that. If you can provide me some help on how to do that or how to find the dumps, I'll be glad to provide that information. Since it is an embedded system (headless Raspberry Pi) and not a full blown desktop Linux, some tools might not be available. BR Hans-Peter A good start would be to strace the journald process while this happens and check what the last syscalls are that it does. Yeah, strace would be nice. You can just do (as root): strace -p $(pidof systemd-journald), and then trigger the bug. Created attachment 94770 [details]
strace
strace for process systemd-journald when crashing after pulseaudio start/stop
I've triggered the crash again and attached the strace output as compressed file. BR Hans-Peter Maybe I made a mistake when uploading the trace because klicking on it yields binary output. You can store it as strace.log.gz und uncompress it with tar -xvzf strace.log.gz. Please let me know if I should upload it again as ASCII file or if you need more trace data.

once again with correct mime type
let's close this. I am pretty sure this has long been fixed. if not, please file a new bug on github. |

I'm trying to run pulseaudio as service on a headless Raspberry Pi platform with most recent packages: ArchLinuxArm OS : Linux 3.10.28-1-ARCH systemd 208-10 pulseaudio 4.0-6 Starting and stopping pulseaudio via systemd regularly leads to system-freezes during shutdown caused by systemd-journald crashes ("out of memory" is the last console message). I was able to simply reproduce this by issuing the simple command sequence: pulseaudio --daemon pulseaudio -k In about every second case this leads to crash of the systemd-journald process with a subsequent restart. Probably because the restart isn't possible during shutdown the system freezes. Systemd-developers should be able to handle any misbehaviour of daemons when shutting down daemons.
