Summary: warn when running out of diskspace in /var/tmp, now
this causes kde system crashes (krunner, kwin,
plasma-desktop,...)
Product: kde
Version: unspecified
Platform: Gentoo Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: wishlist
Priority: NOR
Component: general
AssignedTo: unassigned-bugs at kde.org
ReportedBy: christian.andi at aon.at
Version: (using KDE 4.4.2)
OS: Linux
Installed from: Gentoo Packages
I had a problem that was not easy to find, kde worked correct for a long time
(only minor program crashes) but some day after emerging an app and some
packages one to another kde system application (e.g. plasma-desktop, kwin,
krunner, ...) crashed. I logged out and tried to log in, but kde did not start
anymore, kwin crashed with a backtrace like this:
Application: KWin (kwin), signal: Bus error
[KCrash Handler]
#5 0x00007ffb8246308b in KPixmapCache::Private::mmapFile(QString const&,
KPixmapCache::Private::MmapInfo*, int) () from /usr/lib/libkdeui.so.5

const&) () from /usr/lib/libkdeui.so.5

/usr/lib/libkdeui.so.5
#10 0x00007ffb82463b79 in KPixmapCache::timestamp() const () from

#11 0x00007ffb81e96c8c in Plasma::ThemePrivate::setThemeName(QString const&,
bool) () from /usr/lib/libplasma.so.3
#12 0x00007ffb81e96f7b in Plasma::Theme::settingsChanged() () from
/usr/lib/libplasma.so.3
Afterward I installed the newest kde packages (kde-4.4.2, before it was
kde-4.4.1) but that did not resolve the problem. So I searched the internet
using some keywords of the backtrace and found this bug report:
https://bugs.kde.org/show_bug.cgi?id=233127.
The user had the problem that /var/tmp runned out of space, so I looked on my
/var/tmp/ partition and df showed 100% usage, 0 free. After cleaning up
/var/tmp, kde started up flawless and all problems disappeared.
It took me several hours to find the problem, so it would be nice if kde warns
the user when /var/tmp/kdecache-USER directory runs out of space! It would be
also nice if all routines writing to a full directoy would show an error saying
something like "Out of diskspace: please free some space in /var/tmp/ to
continue <RETRY>" instead of crashing. I think it would save much time for
other people and eliminate some bugs related to this.
Thank you all for the great KDE!
