[Pkg-utopia-maintainers] Bug#1116638: pipewire-pulse leaks file descriptors, exhausts system limit

[Tim Connors]

Package: pipewire-pulse
Version: 1.4.2-1~bpo12+1
Severity: normal
Tags: upstream patch

TL;DR:

Stock KDE interaction with stock pipewire, demands a greater number of
open file descriptors, than stock systemd permits.

Also affects firefox

Wim Taymans in #4047 has linked to a commit that just landed that
might fix the issue (short lived streams trigger it - which would very
much describe firefox which wants to open a new stream for every tiny
little sound effect):

 cfde4c1b for issue #4901 (closed)

Please backport that commit to stable (oldstable would be nice too,
but probably out of the question).
