OK. I've now got two -current machines (both PC's) that exhibit the ftp
stalls (between DEC-based Netgear cards in 100baseTX, half-duplex
operation). Note that I pretty much have to be at the console to see
this behavior and it seems to jam up after a good bit of data is sent
through. I tried playing with some of the sysctl variables, but
couldn't get much change in behavior. The netmask and broadcast are
correct (255.255.255.128 / 18.104.22.168).
So, anyone have any more thoughts? This should be easy to reproduce--
just make sure you're not on an active network terminal link to the
server machine. A watchdog can unfreeze the connection, as apparently
can any traffic to/from the server.
I'd like to get to the bottom of this ASAP, and I'd welcome any suggestions
on how to do so. I know precious little about the networking code...
