[Solved] Transmission on device w/limited hardware resources

[skakz]

Hi all!
I'm running transmission-daemon on a Seagate Dockstar, 1.2 GHz Marvell Kirkwood 6281 ARM-compatible CPU and 128Mb RAM.
Controlled by a windows-machine via tranmission-remote-gui.
The problem is that tranmission use all the free ram resulting in slowdowns to the entire system and timeout of remote-gui.
Then I've no other option to enter in ssh and kill tranmission myself.

It occurs especially with torrents with large files, or when I've few torrents in downloads..

currently running tranmission 2.33-r1 on gentoo (also tried on archlinux)
I have attempted with ulimit and limits.conf but result in kill (forever) transmission when reach the memory limit

Is there some trasmission settings that can I modify to limit/minimize the memory usage?

here other details:

Hi Skakz,

The first thing I'd try is lowering your memory cache from 100 MB to something smaller.

thanks.. it works now.. I don't know why I was thinking that option was a "low disk space alert option"..
