[X-Servers] "Clear" a hung port?

[Peter Krug]

XServerfolk,

I am running Server 10.3.9 on a G5 tower.  One of the services I am  
running is an MYOB FileEdge server to share a single data file among  
3 licensed users - it is shared via an MYOB control panel that lets  
you turn on/off sharing and set the port the spftware uses to share  
the file.  My problem is that one of the users of the software gets  
bumped off her network periodically, which causes the server to think  
she is still logged in because she does not log out properly.  At  
that point, one of our 3 licenses is lost until I restart the Xserver  
because the serving software still thinks this person is using the  
data file. I cannot turn sharing off via the control panel for the  
same reason.

I can force quit the control panel via Activity Monitor to stop  
sharing the file, but unless I change the port, when I start it back  
up we still have the logged in user problem.  I am wondering if there  
is a way to "clear" the port of all network activity to bounce this  
phantom user off the server.  IF there is a terminal command for  
this, it would be wonderful because I could do this remotely.

Sorry to be so long-winded.  Thanks in advance for any help.

Peter
