Thanks.  So would more threads set in AF-Packet  help with this too.
 
I only have one thread set on each interface in af-packet configuration within suricata.yaml.  I notice when Suricata initializes that it says something like either 14 or 18 processing threads  initialize and 3 management threads.  Something like this.  Is it specifying af-packet processing or just Suricata packet processing.  I am using a quad-core i7 processor,which has 8 threads in it.

Hi,
 
A packet can't be send on an interface because it is too long. 
 
Is defrag set to yes in af-packet configuration ? If yes, can you try with no ?
 
BR,

I am using 1 thread in AF-Packet.  My kernel is 3.2.0-23-generic.
