[Description] The machine suddenly stops to be connected to the network. Running "ifdown eth0" "ifup eth0" the network starts to work again for few minutes and then the failure happens again. It is not even possible to ping the machine. /var/log/messages does not report anything wrong. I instrumented the kernel with SystemTap to see what happens when the machine is in the failure state. the function ip_rcv is invoked. the function ip_rcv_finish is invoked. the function ip_local_deliver is invoked the function ip_local_deliver_finish is invoked the function tcp_v4_rcv is NOT invoked When the network works the function tcp_v4_rcv is invoked. Let me know if you need more information. Below all the detail about the machine. Thank you in advance Sebastiano [Kernel version from /proc/version ] Linux version 3.11.0-rc2+ (root@cache.pdbg) (gcc version 4.7.2 (Debian 4.7.2-5) ) #5 SMP Thu Aug 1 14:20:35 CEST 2013 [Processor
