I have compiled PA 9.0 from sources on ubuntu 16.04. I use only required
dependencies.

asyncmsgq.c: Assertion 'a->asyncq = pa_asyncq_new(size)' failed at
pulsecore/asyncmsgq.c:66, function pa_asyncmsgq_new(). Aborting.

I use it as a regular user with the following config:

#!/usr/bin/pulseaudio -nF

.fail

load-module module-native-protocol-unix auth-group=app
auth-cookie-enabled=false srbchannel=true

### Automatically move streams to the default sink if the sink they are
### connected to dies, similar for sources
load-module module-rescue-streams

### Make sure we always have a sink around, even if it is a null sink.
load-module module-always-sink sink_name=null

### Honour intended role device property
load-module module-intended-roles

### Make some devices default
set-default-sink null
set-default-source null.monitor


I spawn it using systemd:

[Unit]
Description=App PulseAudio

[Service]
User=app
Group=app
WorkingDirectory=/home/app
ExecStart=/opt/myapp-1.0/bin/pulseaudio --high-priority=1 --realtime=1
--disallow-exit=1 --exit-idle-time=-1 --log-target=syslog --no-cpu-limit -F
/etc/pulse/app.pa -n
Environment="LD_LIBRARY_PATH=/opt/myapp-1.0/lib"
OOMScoreAdjust=-100
KillMode=process

LimitNICE=31
LimitRTPRIO=-99

LimitNPROC=64000
LimitCPU=infinity
IOSchedulingClass=realtime
IOSchedulingPriority=1

[Install]
WantedBy=multi-user.target
Alias=myapp-pulseaudio.service

It happens quite frequently, every a few minutes.

There are loads of free memory and other resources on the server.
