Thanks to:
Scott Croft for a kill -HUP
Larry Snyder,Timon, Wade Stuart, for lsof
Jon Andrews, Terry Gardner, Facey, Aaron, Stuart Whitby
lowering 'tcp_time_wait_interval' to 60000
Dave leach gave some great links explaing things also:
http://www.unixguide.net/network/socketfaq/2.7.shtml
http://www.unixguide.net/network/socketfaq/4.5.shtml

And especially Darren Dunham for repeatedly explaining something I was
missing  and mentioning both lsof and the 'time_wait'.

Thanks a lot folks.


Original question:
> Greeting on Monday folks.
>
>  Is there a way to 'flush' what Solaris8 thinks is using ports?
> In other words I want to 'zero out' all connections to or from a sun box
> without ifconfig down if possible.
> The scene is thus: I have a number of application servers that talk to
> web and DB servers. If the application dies[1], even after waiting a
> grace period netstat shows a lot of consistent connections to ports that
> the application server uses, and they won't go away. This causes the
> application server to fail upon restart.
>
> I think what I am after is functionality like flushing the arp cache.
>
> I'll summarize.
>
> Thanks,
> -tm
