Just as a heads up, BTW -- if you have upgraded, and now have the larger window sizes, you might also need to bump nmbclusters. I ran into some problems on a high volume web server where the change in sendspace resulted in far more mbuf clusters in use with disconnecting dialup users. With a big flood of connections coming involving heavy data transfer, larger FTP sites may need to make the same change (or at least, keep a close eye on netstat -mb).
