Details:

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.
