Screenshot from wireshark can be found in the attachments.208.134 is the server
IP address, and it's looks like it talking to itself via the lo interface,
im wondering if this is a normal behavior or not.and regarding the Ganesha
server logs, how can i debug it to find why the servers not responding to the
requests on time ?
