Maybe I am wrong, but didn't MLDonkey request data from the other
client in frame 104 with opcode Request Parts (0x47)?

Then the other client sends frame 105 & 106, apparently no EDK
data, thats it. For now I see no bad behaviour of MLDonkey.

When downloading a file on the eDonkey network I spotted, that a HighId eMule source once reported queue rank 11, and with the next connection after 10 minutes the rank became very high (>2000). I let tcpdump do it's job and had a look at the communication. Note that my client also has a HighID

Every 10 minutes, as expected, MLDonkey connects and queries for the source. The returned queue ranks decrease each connection. Once it gets low, I see a connection from the other peer and a OP_ACCEPTUPLOADREQ message from him. Unfortunately all it gets from my MLDonkey is a connection close. With the next connection from MLDonkey I again see a high queue rank.

It looks like MLDonkey is not expecting this message and drops the connection.

Attached a tcpdump of the communication with protocol decoding from Wireshark. The "slot given" message is received at frame 101.
