Hi Matt;

I see one thing that is immediately sticking out as being strange:

> New connection received from 0xe12ce0 [1192.168.1.153  ] sockfd=7.

Can you verify that the address of the client machine is not 
'1192.168.1.153'?  I am not sure if this is the problem or not, but its 
worth checking.

Thanks;
