Hello Noël, This isn't readily reproducible on my system. (In fact, the last time I recall it happening before June 28th was on an Ubuntu 11.04 system over a year ago.) It happens so infrequently that it's more of an inconvenience than a real problem. I haven't looked at the code, but perhaps it's a rare race condition through a shared data structure. I will try some more transfers with the -d option and report back if I am able to collect debugging information. Thank you for your work on lftp. tony
