Does "ifconfig sl0 down; ifconfig sl0 up" help, or do you have to kill
and restart slattach?

Does "ifconfig sl0 delete; ifconfig sl0 address rmtaddr" help?

When you're experiencing the problem, what do packets going out the
line sourced from your machine look like?  (e.g. tcpdump -n -i sl0 icmp;
ping somehost).
