Daemon can hang after [null-sink] asyncq.c: q overrun, queuing locally

Created attachment 124804 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.
