And when it's *out* of swap space, it'll be even worse. The OP has two
problems, both of which could be significant. Out of swap is, for certain.

Kris: if so, his loss.
Ross: add more swap space, and perhaps your system will behave a tad
better. 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).
