Hello. It looks like: Ktorrent raises the nofile soft limit to hard limit and spawns http kio helpers. Because of changes done in the #1070322 kioslave5 process tries to close 1_073_741_813 file descriptors (in my case) Then ktorrent kills these helpers on timeout (because more than 10 minutes is required for the loop) and shows connection error for trackers.
