I saw the dmesg and noticed this at the bottom: Interrupt storm detected on "irq18: uhci2"; throttling interrupt source Interrupt storm detected on "irq16: uhci0"; throttling interrupt source This indicates USB, if so try adding usbd_enable=3D"NO" to /etc/rc.conf. Try limiting the amount of clients able to connect to your webserver, so you can serve those which do get access well. I have the following in my /usr/local/etc/apache/httpd.conf (I'm using apache): KeepAlive Off MaxClients 50 MaxClients is (avail. RAM / size of each process) minus some housekeeping. Your server should not swap. Since KeepAlive is off it can serve more clients than 50. > Would abandoning amd64 and installing a i386 system help?
