I have a 1.0 box hooked up with a slip line. After several
minutes of use, packets cease to flow. Attempt at pinging
the other end of the slip line yeilds:
	ping: sendto: No buffer space available
Any attempts to clear the line back up fail (restarting
slattach, ifconfig down then back up, ...) (rebooting
does fix the problem temporarily)

So, question, what buffer is this that isn't available?
(pstat says I've got plenty of unused swap)
How do I get more?

thanks
