I've a similar issue like you with Deluge. A post that describes what I 
see in my /var/log:

TCP: Possible SYN flooding on port 53126. Dropping request|

A workaround in this case it's disabling SYN flood protection in the 
kernel, adding to /etc/sysctl.conf
     net.ipv4.tcp_syncookies=0

but it's not a real solution.
