no, the sensor monitor only ~100mb/s of traffic with a

stream4 can reassemble tcp streams. If an alert is
triggered by
this packet than the unified output plugin will
decompose this
packet to the original smaller ones.
The alert is associated with the first packet, all
further packets
are marked as tagged packets.
Thanks for the explaination.
So, what must i do to never get this tagged packet alerts?
You will always get tagged packets for events on reassembled streams and
for any rule that has the tag keyword. You can associate these events if
you are using barnyard by the event ID, SIP, DIP, and ports IIRC. If you
are using BASE this is pretty easy to do.
Check out this post for a little more information.

removing the logging of the tagged packets would make analysis
impossible in many cases.
