Public bug reported:
Feisty Beta version. Under high file IO load (such as during an OS
update), the system will crawl. Music will skip, firefox will freeze,
all other apps will freeze. Finally, after several minutes, if the
memory use is high, the system will freeze as a whole and no other
operation is possible (mouse pointer included). Edgy did not have this
problem.
To reproduce for me, I simply need to run several programs (firefox,
Update Manager, ktorrent, totem). I have 512MB, this problem usually
appears when I have swap shut off. It isn't purely running out of
memory, because I can routinely do exactly the same activity (with swap
off) in Edgy and get only a mild slowdown, whereas Feisty hangs. It
appears to be going slower and slower until you have to wait 5 or six
_minutes_ to, for example, switch to a console.
I realize that this bug report is somewhat useless, I've tried to come
up with a clearer way of reproducing the bug, but can't do it. With
this bug, Feisty is unusable to me.
