There's an article in the manual; see also swapon(8) and /etc/fstab. Re: watchdog timeouts, see dc(4). If you are on a ISP that has some performance problems (mine seems that way), that could be it. Also, check your other network equipment; if you have any way, for example, to test with a different switch/hub/router, and to try different settings for the adapter (duplex/half, etc.), it might be worth a try. Or, you could always change your ethernet card (unless we're talking about laptops here).
