[pulseaudio-discuss] On SHM related Bus errors

[Colin Guthrie]

Hi,

There has been some discussion about bus errors and SHM of late.

I've just seen my first bug report on the topic!

https://bugs.kde.org/show_bug.cgi?id=236524

Extract (5 is the lowest number in the call stack due to the crash handler)

Application: KNotify (knotify4), signal: Bus error
[KCrash Handler]
#5  0x00007f071225df5e in pa_shm_create_rw () from
/usr/lib64/libpulsecommon-0.9.21.so
#6  0x00007f0712252676 in pa_mempool_new () from
/usr/lib64/libpulsecommon-0.9.21.so
#7  0x00007f07152a8958 in pa_context_new_with_proplist () from
/usr/lib64/libpulse.so.0
#8  0x00007f0718c33d08 in Phonon::PulseSupport::PulseSupport
(this=0x6de530) at
/usr/src/debug/phonon-4.4/phonon/pulsesupport.cpp:712

This happens after a resume from suspend.

What kind of thing can cause this? Non writable SHM area? Full up?

What is the best way to go about debugging this?

Col
