The problem is packet loss. A single buffer is used for reassembly. If you are missing packets when reassembly is done then the old data is still in the gaps...
So to make sure I have this right... mixed data happens when there is packet loss. Turning on "zero_flushed_packets" will prevent the mixing, causing me to see all 0x00 instead. If running "zero_flushed_packets" has a performance hit associated, won't it increase incidence of dropped packets, and make the reassembly problem even worse? Thanks for the info so far guys, keep it coming =) ~Eric -- Eric J. Bowser I-TRAP Internet Security Services 888-658-8727 toll-free 330-658-0123 fax www.i-trap.net ¨Quis Custodiet Ipsos Custodes?¨
