Thanks for the bug report.

'pmap' displays virtual memory (address space), which is mostly not real memory.

Please attach a copy of your /proc/PID/status file. The important field that affects machine performance is VmRSS, and VmData tells you the amount of regular memory allocations.

[Bram Stolk (b-stolk)]

Thanks for the reply. It is 3.7G byte mapped hardware memory, not just virtual.

Thanks for that. I've never seen pulseaudio do this before.

1. Do you have any ideas as to what apps might have been using pulseaudio recently?

2. Is the problem regular? Does it return after a reboot?

3. Does the same problem exist in Ubuntu 19.04 if you boot that from USB? (http://releases.ubuntu.com/19.04/) We use a newer version of PulseAudio in all Ubuntu releases from 18.10 onward so I am wondering if this is a bug that was fixed already.
