Sometimes the NIC locks up completes until it is power cycled. FreeBSD 5.2.1-RELEASE on the same machine has no problems in this area, network throughput as high as 37MByte/s is observed (bottleneck is not the NIC but the 2.0GHz celeron cpu of the server). >How-To-Repeat: The problem machine is gompie, the server humpie runs FreeBSD 4.10-RELEASE rudi@gompie> rsh humpie dd if=/dev/zero bs=16k count=1000 | dd of=/dev/zero obs=16k The command never completes.
