Hi,

	I am using TCP/IP stream sockets between two hosts.  I know that when
either of the processes die, the other process will receive a readable
signal on
the stream but the read will return 0 bytes, basically telling me that the
line has died.  However, I have a problem when one of the hosts crashes.  The
connection stays up, I can still write on the stream, but obviously I can not
read.  Is there some sort of procedure to detect a crashed host versus a busy
host?

			Thanks in advance.
