FTP'ing an image from server to client resulted in the client aparrently losing the plot at layer 3 - a ping running simultaneously stops responding at the same time. This proved to be extremely repeatable. Doing ifconfig dc0 down, then up again fixes the problem temporarily. There is nothing in either dmesg nor /var/log/messages about this, and netstat -m shows nothing abnormal. Is this a known problem? RTFM'ing a little I see a recent CVS commit (http://www.FreeBSD.org/cgi/cvsweb.cgi/src/sys/pci/if_dc.c), version 1.54 "Deal with the condition where we lose link in the middle of transmitting a bunch of frames."? Is this therefore fixed under 4.4? BTW, as a short term fix, the same machine has a realtek chipset so I swopped the configuration over and all is good. Must do the 4.4 upgrade (sigh).
