Thomas, removing the upload limit you probably didn't solve the problem at all, you simply tricked another problems that deactivates UDP completely and, thus, ‘solves’ your UDP problem as a side-effect (but things work worse, not better, as in that case UDP is not used at all).

See open bug #21992 regarding that UDP problem.

IMHO this bug should be re-opened.

I don't know if it's important.
In my syslog i have often this kind of line :
Jan 23 16:19:11 serveur2 kernel: __ratelimit: 1 callbacks suppressed

Maybe this can help you

Hi,

I raised the config value to 1.000.000, after 1.500.000 and after 2.000.000 and i still having exceptions in my sockets:
Jan 23 15:52:22 serveur2 mlnet: [TCP_BS]: BUFFER OVERFLOW 485846+16397> 500000
Jan 23 15:52:22 serveur2 mlnet: MESSAGE: [
...
...
]

and from syslog :
Jan 23 15:53:13 serveur2 kernel: Neighbour table overflow.
Jan 23 15:53:13 serveur2 mlnet: [udpSock] Exception sendto failed: No buffer space available in sendto next
Jan 23 15:53:13 serveur2 kernel: Neighbour table overflow.
Jan 23 15:53:13 serveur2 kernel: Neighbour table overflow.
Jan 23 15:53:13 serveur2 mlnet: [udpSock] Exception sendto failed: No buffer space available in sendto next
Jan 23 15:53:15 serveur2 kernel: Neighbour table overflow.

in raised other limits too :

max opened connections : 200
and max upload rate : 500

I have more and more error log message when i raise client_buffer_size

Other idea ? Can i give you some other informations ?

Try to raise this value:

(* Maximal size in byte of the buffers of a client, minimum 50.000 byte.
For high-volume links raise this value to 1.000.000 or higher. *)
 client_buffer_size = 500000

I've downloaded and compiled the last release from www.mldonkey.org
My computer os is debian (etch).

On this computer, i have a lot of bandwith (100M).

At the begining, i disabled all transfers limits, and setted max opened connections limit to 200. I have enabled edonkey, bittorrent, overnet, kad and ft protocols.

The problem is that the buffers (sockets) are too much full. When they are full, i can't connect to the server by ssh. when i'm already connected, the server can't do anything (no ping, no connection).

After this, i setted some limits, but now, i have very small limits, and i've still the socket buffer problems :x

I don't know if this is a bug or i have do something bad.
i wanted to post on the forum, but registration is close for the moment.

I put my downloads.ini as attachment, tell me for more informations.

PS: Sorry for my bad english, i'm French.

(Note: upload size limit is set to 16384 kB, after insertion of the required escape characters.)
