ultrix not closing down network connections?

Either the kernel isn't closing down connections properly or netstat
is listing connectins that it shouldn't. The belch machine gets lots
of ftp traffic. The last five ftp connections shown here have been
shown by netstat for several weeks now (and there aren't any ftp
daemons running that would correspond to them either). The Local
Address 2323 socket one is a daemon program of mine and I can query
the program to see what connections it has open and it doesn't list
any active connections either, so that's another zombie connection.
It's also interesting that these are all listed under the Foreign
Address column with their numeric internet address rather than their
symbolic name; there are plenty of other normal connections that
netstat lists by their symbolic name.
