Bug#368546: general: remarkable slow-down of whole system after 4-6 hours

Package: general
Severity: normal

i'm very sorry to report a other/general bug but because i could not
figure out which package is responible for the behavior i try this.

my system slows down after some hours of activity (4-6). i use that
system as desktop, using linux 2.6.16, xorg (dual screen), gnome,
sawfish and severly tools (i.e. vim, firefox, gajim) mostly for

since an upgrade (i think to the xorg system with seperated packages
for drivers) i notice a slowdown of the whole system after some time.
the load in top shows values of 2 and more without any program running
(after closing firefox, vim, etc) while the system is 98% idle. no
noticable memory is used (the system has 2GB ram), swap is mostly

opening a window takes seconds. switching focus shows visible drawing
of the highlighted frame. after a x-restart the system is faster but
only for a short time. 

all this looks to me like a memory leak. but where? system ram is not
used. it looks it could be related to sawfish, xorg or linux itself
(agp module?). i use dual screen only at work and i think (its just a
feeling) that with only one screen the system stays fast longer.

i tried google to figure out if someone else has this problem without
any success... can you point me where to look for the bug or what to
do? i'm neither a x11 nor a linux developer but a quit good c
programmer - can you help me in tracking down what's going on?
