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)

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

Hello Yang! Please unmask and update to KDE 4.5.3 or later! I have tested the case again now in KDE 4.5.3 in Gentoo x86_64 under similar conditions for several hours, this bug was ironed out(resolved). "Kdeinit4: Kiothumbnail" is started once the thumbnail view is requested via Dolphin "thumbnail" button consuming 20-40 MiB of RAM. Thumbnails are displayed rather fast. Then, it idles for around a minute or two and is killed.

Well, amarok behaves in a similar way in the cover art manipulation. In this case, how does it manage to hang all the resources with a few tiny pictures? With this KDE is a real mess...

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.

This is not related to KUbuntu, but its KDE 4.3.3 problem. If there will be solution, please upstream it! Im currently running x64 gentoo system, based on Calculate linux 10, which is actually prebuilt gentoo. Machine is dual-core E5300 with 4Gb of ram. Im experiencing SAME issues with kio_thumbnail, slowly eating memory up, even if im NOT browsing (or browsed) any pictures and did not open any miniatures. The effect is so insane, that this machine left for 6 hours for a purpose of backing video up(scratched dvd) has experienced kernel panic, because it run out of memory! (4Gb ram + 4Gb swap). See two small examples in attatchment. This is a very serious bug, it prevents normal work even if system is running stock and untouched. ** Attachment added: "kernel events on kio_thumbnail memory overfollow" http://launchpadlibrarian.net/38234678/kio_thumbnail_memleak.txt -- 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-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

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
In Kubuntu 9.10: Something similar applies to PDF documents. If you have a directory containing several large PDF documents, and you have preview enabled, konqueror (or dolphin) effectively freezes. Even if you turn preview off, there seems to be no way of disabling a preview component for the right-click properties dialog for PDF files. The same applies with tootips - you get a pdf preview, and that can take a long time. So you have to run without preview and without tooltips, and even then you must take care not to attempt to read the properties of any large PDF. This is an absurd state of affairs. Except for large single image PDF files, the preview image should be the first page, which is unlikely to be very large. It should be possible to get the first page without reading the whole document, which is what seems to be happening. For certain kinds of usage, where you habitually deal with large PDF documents from other sources, this kind of thing is a road block for karmic + KDE4. -- 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-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
[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 Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
