What it means is that the IPFW code didn't see a long enough packet to contain enough data to be logged usefully. That could be a sign of hardware problems like a flaky cable or a NIC that is going wonky: if you can check "netstat -i" and look for excessive input errors or collisions. If the machine is connected to a managed switch, look for "runt packets", smaller than 54 bytes (56?, whatever the minimum valid size is).... -- -Chuck
