Ports in close state

[coruscare]

I have a machine running redhat 6.2 and samba 2.0.6 that does a persistent mount to my Windows 2000 machine for the purposes of serving files via FTP.
The samba connection occasionally times out it seems, I get the message
smb_request: result -32, setting invalid
smb_retry: new pid=20679, generation=12
and it generates a new connection
I've got SO_KEEPALIVE active in the socket options in my SMB.CONF to try and maintain the connections.

The problem is that when it generates a new connection, the old connection port is left in a CLOSE state for a long time, occasionally long enough that it manages to crash the server (Based on the log I think PROFTPD helps crash it but I'm not sure.)
