Accounting-Request packets

Hi guys, Not to waste too much time, but I can't seem to find answers to two quick questions and I was hoping someone might know off the top of their heads: 1) Can a radius accounting session get the Start message from one host and the Stop message from another? 2) I've got wireshark showing incoming radius messages on a box here; but freeradius -X isn't showing them being spotted; if the a-v pairs weren't spot on, would if just silently discard the packets? Would it not even log that malformed packets were received? Thanks for your time, -- Mark Dennehy
