for example in gwenview (the thumbnailbar) or when copying a big image
file in konqueror that already exists .. (when the window to compare the
two versions is started) kiothumnailer is startet and it takes one
minute and the whole system is unusable.. this process should NEVER get
(or take) that much resources.. even if i had dolphin set up to show
300MB thumnails.. (i have not)

I'm having the same problem with latest SVN. kio_thumbnail uses a lot of
memory and CPU, and takes a lot of time to free the used memory.

and here's my 2 {$COIN_DENOMINATOR}
Summary:
kio_thumbnails really missbehaves by stealing memory for me too (+1.7G DATA as
reported by top this morning). Can't say about the CPU usage as it fills RAM
and swap causing massive swapping => skyrocketing my load avg to +30.0, top
says mostly (+95%) io wait untill I manage to kill the kio_thumnail process (or
processes)), this probably due to thrashing caused by the exess memory theft.
(I'm puzzled as to why it's not OOM killed!)
Versions:
OS: Gentoo
kde-base/kdebase-kioslaves-4.3.0
(build with USE=debug so it should be possible to get some
useful debuggging info, not sure how though)
$ kde4-config --version
Qt: 4.5.1
KDE: 4.3.00 (KDE 4.3.0)
kde4-config: 1.0
Reproduce:
It usually starts by hovering big movie files or folders with big movies
files. Though it shouldn't thumbnail them, max previev file size is set to 5 MB
(the movies as much bigger than that), the thumbnails button isn't checked.
Further more only "Grafik" (I'm 'guessing' the non localized string is
"graphics") and Jpeg is selected. And "Använd miniatyribilder inbäddade i
filer" (~= "use embedded thumbnails"/"use thumbnails embedded in files").
* Clearly kio_thumbnails/dolphin isn't respecting those options. - maybe this
is a konqueror/dolphin bug? (otho, imo thumbnailing a file shouldn't consume
more than _tops_ 10M RAM, or perhaps I'm living in a fantasy world?)
Work-around:
I've temporarily renamed kio_thumbnail.so to kio_thumnail.so.disabled, since
it's a hazard to the system's stabillity right now.
Wish:
A kill-switch for kio_thumbnail, i.e. a "Never generate thumbnails" option, if
so only accessible via manually editing ~/.kde4/share/config/kio_thumbnailrc.
Or a hard memory limit option there, say 100M (which imo is too much, but at
least a limit that should prevent grand-theft-ram).
Or better yet, a real fix that makes kio_thumbnail use a reasonable amount or
RAM when generating thumbs.

I can confirm this. I turned on previews/thumbnails for most file types
(as it's a very cool feature) and then went about normal usage with
Konqueror. After not long I found several kio_thumbnail processes
chewing through resources like it's going out of style, the most
flagrant of which goes something like this in top:

This is still happening on Kubuntu 11.04 with KDE 4.6.4. Opening a folder with lots of tiff files will make kio_thumbnail to use a lot of cpu and the process doesn't come to an end unless it's stopped manually. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-runtime in Ubuntu. https://bugs.launchpad.net/bugs/289338 Title: Extreme memory usage by kio_thumbnail To manage notifications about this bug go to: https://bugs.launchpad.net/kdebase/+bug/289338/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
[Bug 289338] Re: Extreme memory usage by kio_thumbnail
Tried to give a non-mono application a try and got upset with it. Not only digikam is strange that it does not find images when an album is specified, it eats up all resources and completely freezes my system. I do have 4 gb of photos, digikam uses all resources to "add" a little fraction of it - a folder worth of 200 mb. If a new user sees f-spot or this even worse digikam, he/she might get a false impression about Linux. I myself use ImageMagick, gthumb, and eog... -- Extreme memory usage by kio_thumbnail https://bugs.launchpad.net/bugs/289338 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-runtime in ubuntu. -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
[Bug 289338] Re: Extreme memory usage by kio_thumbnail
In fact System Monitor shows konqueror/dolphin eating a large percentage of CPU, so perhaps it's not kio_thumbnail. And at some point konqueror spawns pdftotext.

[Bug 289338] Re: Extreme memory usage by kio_thumbnail
This is most definitely still a problem, even in a new Jaunty install. It is particularly pronounced with directories of multipage tiff files. kio_thumbnail processes get launched until all available memory is exhausted, swapping out the entire system until nothing works. Before the system freezes up completely I counted 6 instances of kio_thumbnail at ~200MB each on a 1G memory box. ** Changed in: kdebase-runtime (Ubuntu) Status: Invalid => New ** Changed in: kdebase-runtime (Ubuntu) Assignee: (unassigned) => dwchapin (daren-chapin) ** Changed in: kdebase-runtime (Ubuntu) Assignee: dwchapin (daren-chapin) => (unassigned) -- Extreme memory usage by kio_thumbnail https://bugs.launchpad.net/bugs/289338 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-runtime in ubuntu. -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
