Hi,

how could i go about trouble shooting this: i've run all automatically recommened updates and lately (maybe since 2weeks) i've run into terrible memory disk swapping. Atleast i assume thats the problem, the disk keeps making a lot of IO operations (by sound) and everything freezes for seconds at a time. I've done nothing special only installed the updates.

Running FC10 on a intel dual core 2.3Ghz with 1GB or RAM. Its clear that some of the updates did this as it was very enjoyably fast before. Among updates was atleast one kernel update i think.

$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup01-LogVol00
151623852 46622068 97299668 33% /
/dev/sda1 194442 28251 156152 16% /boot
tmpfs 495400 980 494420 1% /dev/shm
/dev/mapper/VolGroup00-LogVol00
187117284 98132604 79326312 56% /mnt/arc

CPU is flat-lining and i got maybe firefox and Evolution open.. horrible freezing.. unable to move mouse accross the screen with out it lagging like it likes it.

Right now closing Evolution seemed to help a lot, but is it really the underlying problem? I hadnt been on for long.

I had rtorrent running and VLC on pause for many hours. Pulse-audio seemed to be running pretty high with 160MB RAM for being paused.

Attached htop screenie from after i closed some stuff.

Can you run at the terminal:
top
iotop
lsof

Have each on its own terminal.
Or Ctrl+Esc for KDE which is graphical.

iotop's a gem, thanks :) Taking off Gnome desktop effects seems to have helped a lot.

I'll take this chance to express my opinion about updates making GUI-login not work: http://www.smileyhut.com/naughty/axe.gif Wasnt even the first time, lol :)
