I’ve installed manjaro-pipewire on Manjaro Gnome 41.2, but the pipewire process is leaking my system memory (128GB of RAM) until it’s full and constantly putting 100% load on a single CPU core. The system will regularly hang or be unresponsive for some time and the pipewire process starts over again leaking memory until the system memory is full. This goes on for 3-5 times and at some point the entire system is unable to recover and just freezes.
Needless to say that the audio settings in the gnome control panel don’t offer an audio device in the list and applications using audio (like Firefox) regularly hang and behave in weird ways as long as this cycle is happening.
This is what I find in journalctl --follow after restarting the pipewire process and waiting for it to reach about 50GB of RAM usage:
