Bug ID: 96749
Summary: Daemon can hang after [null-sink] asyncq.c: q overrun,
queuing locally
Product: PulseAudio
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: major
Priority: medium

gdb dump
Version 9.0.
I have connected many (+/- 100) GStreamer based clients over native protocol
with disabled SHM and realtime scheduling.
Each client that has GStreamer's pulsesink loads module-null-sink and sends
data to this sink.
Each client that has GStreamer's pulsesrc loads module-null-sink and fetches
data from this sink's monitor.
Sporadically I load loopback module to "connect" these null sinks and their
monitors.
It works fine for a while and then loads of
[null-sink] asyncq.c: q overrun, queuing locally
appear in the syslog.
All operations of PA are stopped. It's not desired behaviour, even if there's
something wrong with some of the clients it should not cause whole daemon to
hang.
Stack trace is attached.
