>Description:
Network (sk0) hangs when moving a large amount of data across the
interface. What I'm looking for is help on how to track down whether
this is a hardware or a software problem.
>How-To-Repeat:
Using ssh and tar, I copied over about 2G of data from one FreeBSD box
to another via:
source% tar cf - . | ssh target "tar xvf - -p --atime-preserve"
Eventually the network hangs.
>Fix:
Currently when the network hangs, I am able to take the network down
and immediately bring it back up using 'ifconfig sk0 down; ifconfig sk0
up'
