Like Wez is saying, this is not VNC specific. If you had a telnet
session going, and simply disconnected the cable, the telnet server
would be totally unaware of a disconnected client for upwards of 2 hours
(the Solaris default). When you remove the cable, there is no way for
the remote network to tell your server he is gone, and the NDD settings
on Solaris instruct the TCP layer to hang around for quite a while in
case the client comes back, and will therefore attempt to "recover" the
TCP session.
I typically tweak my NDD settings in Solaris to set a keepalive down in
the 1 minute range.
