sysctl.conf:
kern.ipc.somaxconn=1024
kern.maxfiles=102400
kern.maxfilesperproc=10240
#net.isr.enable=1
net.inet.tcp.inflight_enable=1
net.inet.tcp.syncookies=0

Kernel config attached. I do realise that my configuration and kernel source 
is not exactly supported, but I'm not sure this is related to ALTQ - even if 
so, maybe this will help Max avoid a possible problem before ALTQ gets 
merged.
