mldonkey/kernel freeze

Hello,
I'm using mldonkey 2.5.3 and i noticed that it was freezing the kernel sometimes after a few mins, sometimes a bit longer. (my system never crashes in other cases)

I tested it with linux-2.4.20 (xfs-sources, latest) and linux-2.6.0-beta3
I'm getting very much firewall hits sometimes (30-40 per sec)
My configuration in mldonkey allows many connections( 3000) and around 30 conn/sec (defaults are like 300 and 10, but it just takes longer to crash it seems)
This box is also the firewall (bad bad ;P)

When i'm using (way more) connection from computers in my nat, linux doesn't freeze. (eg, using emule and 100 conn/sec, 5000 at time)
Maybe because it goes through NetFilter ConnTrack instead ?

I'll take any suggestion

Same here, no solutions so far

What kind of network interface do you use? I am using a patched nvnet for nforce2 and thought that this one is responsible for the freezes!?

thx..

Same problem in my linux/firewall/router box. I thimk the problem its on iptables. If i open the firewall completly, (remove all rulles and default to ACCEPT on all chains) the crash never happens.

I suggest to post the rules that we use for emule and isolate the problem. Actually im at work and cant post my rules but late at night i will post them on this thread.

oh well, looking for some major knowledge on iptables ive found the most of iptables configuration utility -> "FireHol". Its simple, commmand line based and with most of rules needed included. Fantastic peace of software.

xMule was runnig over 15h without problems. Thanks coders!!!!!

I want to try firehol to have mldonkey working,
what do you have in your firehol.conf for mldonkey ?
I think some ports have to be opened ?

thanks

on the internet interface add the following firehol rules:

to use mldonkey's edonkey network support add: "client emule accept"
to use mldonkey's overnet network support add : "server custom ovnet tcp/8460 default accept"
to use mldonkey's bittorrent network support add: "server custom torrent tcp/6881:6884 default accept"
