FC2 Server freezes when amule starts
 
Hi mates, I have a FC2 server with many services on: samba, email, web server, FTP server ...
Everything works fine as far as I don't start amule, no matter the way I do: amule or amuled. Whenever I start it, I get my server frozen after 1 or 2 days running.

I've configure my firewall with GuardDog firewall tool and I've opened the ports the aMule web site recommends: TCP -> 4662 & UDP-> 4662:4665, 4672

More details about that at: http://www.amule.org/wiki/index.php/Firewall

However, I've realized many packets are dropped and my ip_conntrack gets bigger and bigger everytime what leads in a higher CPU overhead, although not much anyway.

Do you know what might be happening with my PC?

I've tried many things so far, although no success at all. The last thing I've tried is to launch a script which checks whether my IP has changed (I use dynamic DNS) and it such a case, it runs again the rc.firewall script GuardDog creates. It stops all the traffic, empties all chains and rewrites all rules again.


Any idea? :confused:

Thanks for your help. Any tips will be welcome!! ;)
