Public bug reported:
There's a similar bug at:
https://launchpad.net/ubuntu/+bug/34822
but it was rejected.
Computer: Dell optiplex gx620 (P4 3.2 GHz, 512 MB, 1.5GB swap)
Desktop: KDE 3.5.5
On Kubuntu Edgy Eft (kernel 2.6.17-10-386), the system becomes (very)
unresponsive after using it for a couple of hours. It's so bad that I
can't even move the mouse (but the music still plays).
It happens for example at the end of the day, when I try to close xmms
which has been running all the time (~8 hours). It happens also when I
try to reopen an application that has been just sitting and not doing
much (like thunderbird or some documents in openoffice).
It seems as if the kernel has problems loading applications from swap
back to the memory. Superkaramba widgets show me the CPU usage at 100%,
but "top" or "ps -aux" don't show any particular process using the CPU
so intensively. After waiting for about 2 or 3 minutes, the CPU usage
cools down, and I can use the system almost normally - the CPU is at
~2%, but jumps up for any action, even right-clicking on the desktop.
Logging out, and back in puts things back to normal (I guess the swap
and memory get flushed or something).
The problem is reproducable since it happens every day. I guess the
procedure would be to open a couple of applications (thunderbird,
firefox, inkscape, amarok, konqueror, konsole and a few spreadsheet and
word documents with openoffice) and surf the web for a couple of hours
or days and then try to use any of the applications that have been lying
around.
