Transmission

so, how can I solve the problem,
I test on torrent and few connection, but the memory is lowed..

my item is a broadband router and it has a small memory capacity 128MB
I see the losing memory in the overview webpage on my router webserver, when the transmission web gui is downloading a torrent.

but this is the recomded config.
when I start to download, slowly the memory is run out.
sorry I dont know which issue is that.
thx

I have a problem, that when I start one torrent, that the memory is filled .
How can I solve that the transmission doesn't use all free memoy?
thx
