transmission not responding for huge torrent

[lxyu]

env: mac 10.6.7 transmission 2.31(12441)

steps to get transmission die:

1. add a huge torrents file to transmission, for example, 100G.
2. it starts downloading at a speed of about 3 - 4M/s
3. when about 300 - 400 Mb downloaded, pause the torrent.
4. transmission not responding.

bug:

1. At the same time, I can see disk is being written with a speed of 40 - 60 M/s from Activity Monitor. I use iotop to check io stats in terminal, it point out it's transmission.
2. As I have only downloaded 300 - 400 M, but transmission continues to write data to disk at high speed and never stop.
3. I have to kill transmission from Activity Monitor, transmission quit but the io still there and noway to stop. ("ps aux | grep mission" in terminal I can see transmission still there but "kill -9 pid" would not kill it).

And I have to reboot my mac to get rid of it.

More info: About half year ago in Ubuntu 10.10, I tried transmission to download huge torrents(often big than 10G), and I can see the computer become very slow, and from network activity I can see the speed loop at 10M/s for a while then < 1M/s for a while. While rtorrent works fine in the same env with speed at > 10M/s and computer running smoothly.

See #1753.

lxyu: You need to just wait while preallocation is completed. Could be around 30 min. in your example.

So it's a problem 2 years ago..? And still not fixed?
