Today I ran the test from my laptop to my server over my local wifi network
but it seems to behave exactly as it did locally. Possibly this is because the
server is too close. I don't have any other ftp server around that allows
uploads to test with right now.

Anyway, to get back to the problem you see. When it get stuck, isn't it your
app that gets stuck in a select()-loop and it never gets any action on the
socket event it waits for? If so, in what state is the easy handle then? (I
assume you can "attach" a debugger to the running process, like with gdb -p
[pid] or similar).
