	@(#)BUGS	1.6 87/08/29

Isolated sites:
	if a site belongs to a domain from which it is isolated,
	then messages may arrive at it destined for other sites
	in that domain to which it will be unable to deliver them.
	The messages may be returned with the message
		"routing loop detected".
	This is not really a bug, being due to mismanagement
	(cf: installation guide section on domain configuration),
	but it does seem to happen, especially when new sites
	join the network independently that belong to geographically
	distributed domains (such as companies).

Foreign nodes:
	If you introduce a "foreign" node to the network, you
	must ensure that its name is unique. This is because
	the network can only distinguish between nodes of the
	same name if they broadcast their own statefiles to
	inform the network of their hierarchy. But note the
	use of the "hierarchy" and "domain" commands for
	foreign nodes in acsstate(1).

Strange mailers:
	If you use a "mailer" that likes to write on people's
	terminals informing them of arriving mail, and it doesn't
	have a timeout mechanism, then you may find that the mailer
	can hang on output (to a "stopped" tty.) This may hang the
	whole network, as network processes waiting for the mailer
	to terminate bank up, so beware.
