        Answer:

        Eventhought I could not find an answer to my problem as to what is
causing it
        here is a solution to it so if it ever happen again the interface
could be brought up
        as soon as it goes down.

        The following script will monitor the port on the server, this will
be done at the
        crontable.:

        #!/bin/csh
        #
        # Checks for network connection with ping
        # If it can not ping router, ifconfig hme0 up

        ping 111.111.111.254 15 > /dev/null

        if ( $status != 0 ) then
           ifconfig hme0 up
           /usr/ucb/mail -s "`hostname` hme0 reset @ `date`"
youremailaddress < /dev/null
        endif
