Dear List Members:

 dhcpd -tf dhcpd.trace -d >& dhcpd.out

in hopes of getting some more information next time it happens, probably
in a couple of days. Of course I don't yet know how to interpret the
trace file to gain useful understanding of what happens.

Does anyone recognize this problem, or can I provide furhter
information? The dhcp is only serving the private network inside the
