Hi, I'm using FreeBSD 4.3 (I know, a few point versions back but it works great) as a home server. It works great except for one important service. Occasionally when I try to transfer files of size ( > 500 KB), ftpd stalls or takes such an intolerable amount of time that I cancel the job and restart the FreeBSD server. About 1/3 of the time, the restart resolves the problem and file transferring is nice and zippy. When file transferring does stall (or runs at a snail's pace), it stalls in all services that deal with larger files ( again, > 500 KB) - i.e., smbd, ftpd, smptd. It's a given that the problem is software, not hardware. I've finally become annoyed enough with it that I began investigating the odd behavior. The server's got a Netgear FA311 NIC, which may be the root of my woes, but hopefully not. Here are some outputs - 1) /var/log/messages Sep 6 09:08:28 spotted /kernel: Copyright (c) 1992-2001 The FreeBSD Project.
