[plasmashell] [Bug 361521] Insane virtual memory consumption and icon-cache mappings

2016-11-24 Thread Laurent Bonnaud 
https://bugs.kde.org/show_bug.cgi?id=361521

--- Comment #9 from Laurent Bonnaud  ---
Since my initial report I updated my systems to Ubuntu 16.10, Plasma 5.8, and
KF5 5.27/5.28.

The icon-cache problem is solved: the icon-cache.kcache file is only mapped
once.

However the DRM problem remains:

$ grep /drm /proc/$(pidof plasmashell)/maps | wc
3483132   34104

on one system and on the other:

$ grep /drm /proc/$(pidof plasmashell)/maps | wc
2512259   24598

> Do you see the same?

As far as baloo is concerned: yes.  It usually uses 5GB of virtual memory.  But
today I rechecked and it uses an even more insane figure of 256GB !  I wonder
how baloo can work on a 32 bits system :>.

But perhaps this baloo problem deserves a separate bug report.  This report was
about plasmashell.

Here are details of the mappings it uses:

[plasmashell] [Bug 361521] Insane virtual memory consumption and icon-cache mappings

--- Comment #7 from Chris Samuel  ---
Using KSysGuard you can get a full breakdown of the mappings, it turns out for
me I see 5GB is used mapping in my Baloo index file (which is just 420MB in
size), another 2GB is anonymous mapping and then you've got 263MB for the heap.

/home/chris/.local/share/baloo/index

Do you see the same?

Here's the summary from KSysGuard for plasmashell in case it is of use:

Process 2344 - plasmashell

Summary

The process plasmashell (with pid 2344) is using approximately 458.4 MB of
memory.
It is using 447.9 MB privately, and a further 58.3 MB that is, or could be,
shared with other programs.
Dividing up the shared memory between all the processes sharing that memory we
get a reduced shared memory usage of 10.5 MB. Adding that to the private usage,
we get the above mentioned total memory footprint of 458.4 MB.

Library Usage

The memory usage of a process is found by adding up the memory usage of each of
its libraries, plus the process's own heap, stack and any other mappings, plus
the stack of its 24 threads.

I'm seeing this same issue on Kubuntu 16.10 with its Plasma 5.7.5, KDE

I've got Intel graphics, but using the modesetting driver.

Same here on Chakra Linux with:
plasmashell 5.6.3
applications 16.04.0, KF5.21

It seems that the value of virtual memory used increas continuosly.
I have clock/weather/system load/network load plasmoids and nothing else
I don't know if is related but this issues started after the update of nvidia
