Package: transmission-daemon Version: 2.9.2 I have upgraded debian8 to debian9 today, and I find transmission-daemon have a high memory usage now.
At debian 8, it occupied about 100mb memory, but at debian9 it cooupied about 800mb. I simply copyed the old version transmission-daemon from debian8 (other computer) to debian9 (to ensure this could work, I have also copyed some .so files), but it still occupied. Maybe it is some bug of debian9.
