Bad luck Grandpa
Well I did manage to break it last night ... It disconnected after 15 hours or so, but my internet connection closed as well, so either FW did not reconnect and after a period of idleness my internet connecrion closed or my internet connection closed first, which is not anything that happenned before.
Real memroy use by FW had gone up to 1.3 GB and it was not easty to restart it .. fairly well frozen..
