I'm running a connection to a remote server via x2go. The remote desktop is xfce. When I leave this unattended for some time, I come back to find that pulseaudio is sucking 64GB of VM. Needless to say, I don't really need PA running on it, but I haven't seen how to disable it. Also this seems like a bug, PA has no business using 64GB of VM.

I've just been killing it when I notice, but I'd rather fix the problem.

Any thoughts?
