I occasionally lose all network connectivity on my inside nic (sis1). THis usually follows a large data transfer from the server (100Mbit, full duplex). What I see is that from the server console I can ping the nic IP (192.168.0.1), but everything else on that subnet is unreachable. The routing tables are fine and if I do "ifconfig sis1 down" then "ifconfig sis1 up" all is well again. (note that when I do ifconfig down I can't ping the nic IP) I get no error messages or clues - The NIC thinks it is "UP" and no errors. There are no interrupt conflicts or anything but 2 NICs on the PCI bus (it's a micro-atx motherboard with integrated graphics, 1G Celeron and 256M ram). Anyone got any suggestions of where to start on this one? I'm going to try a full upgrade to 4.7 when I get a free day to take the server down, but it's not going to be soon. [The only non-standard thing on this machine is that I've hacked the ata driver to only let the disks go to UDMA66. At UDMA100 the network throughput was slow and limiting the UDMA top speed fixed it.] Neil To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
