Very strange behavior sometimes.
A user, let say mr.X is in my queue at place number 5. Whois responds and I can also browse the list of this user. When browsing I see Mr.X has a file that I'm downloading already so I can add Mr.X.
After doing so, I come in the remote queue of Mr.X (place 68) and try to start the transfer (my upload). The upload doesn't start, it disconnects directly. Why??
This happens not always but from the 10 times I start the upload manually, 4 disconnect directly, 2 time out (while waiting for incoming connection). But I can do a whois and get an answer, can browse their list....
