I need to get a packet sniffer between the NAS and the BSD machine to determine if it is actually getting transmitted across the wire or not. This problem is happening on both fBSD based Radius servers at about the same time. Maybe load related? Only other thing in common between the 2 is that they both have fxp ethernet cards.
