[Touch-packages] [Bug 1834794] Re: Uses too much memory (6Gbyte process)

2019-06-30 Thread Daniel van Vugt
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.

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.
